The following examples demonstrate some low-level uses but a practical program would likely use the higher-level API provided by C or similar instead. use Socket qw(PF_INET SOCK_STREAM pack_sockaddr_in inet_aton); socket(my $socket, PF_INET, SOCK_STREAM, 0) or die "socket: $!"; my $port = getservbyname "echo", "tcp"; connect($socket, pack_sockaddr_in($port, inet_aton("localhost"))) or die "connect: $!"; print $socket "Hello, world!\n"; print <$socket>; See also the L section. =head1 DESCRIPTION This module provides a variety of constants, structure manipulators and other functions related to socket-based networking. The values and functions provided are useful when used in conjunction with Perl core functions such as socket(), setsockopt() and bind(). It also provides several other support functions, mostly for dealing with conversions of network addresses between human-readable and native binary forms, and for hostname resolver operations. Some constants and functions are exported by default by this module; but for backward-compatibility any recently-added symbols are not exported by default and must be requested explicitly. When an import list is provided to the C line, the default exports are not automatically imported. It is therefore best practice to always to explicitly list all the symbols required. Also, some common socket "newline" constants are provided: the constants C, C, and C, as well as C<$CR>, C<$LF>, and C<$CRLF>, which map to C<\015>, C<\012>, and C<\015\012>. If you do not want to use the literal characters in your programs, then use the constants provided here. They are not exported by default, but can be imported individually, and with the C<:crlf> export tag: use Socket qw(:DEFAULT :crlf); $sock->print("GET / HTTP/1.0$CRLF"); The entire getaddrinfo() subsystem can be exported using the tag C<:addrinfo>; this exports the getaddrinfo() and getnameinfo() functions, and all the C, C, C and C constants. =cut =head1 CONSTANTS In each of the following groups, there may be many more constants provided than just the ones given as examples in the section heading. If the heading ends C<...> then this means there are likely more; the exact constants provided will depend on the OS and headers found at compile-time. =cut =head2 PF_INET, PF_INET6, PF_UNIX, ... Protocol family constants to use as the first argument to socket() or the value of the C or C socket option. =head2 AF_INET, AF_INET6, AF_UNIX, ... Address family constants used by the socket address structures, to pass to such functions as inet_pton() or getaddrinfo(), or are returned by such functions as sockaddr_family(). =head2 SOCK_STREAM, SOCK_DGRAM, SOCK_RAW, ... Socket type constants to use as the second argument to socket(), or the value of the C socket option. =head2 SOCK_NONBLOCK. SOCK_CLOEXEC Linux-specific shortcuts to specify the C and C flags during a C call. socket( my $sockh, PF_INET, SOCK_DGRAM|SOCK_NONBLOCK, 0 ) =head2 SOL_SOCKET Socket option level constant for setsockopt() and getsockopt(). =head2 SO_ACCEPTCONN, SO_BROADCAST, SO_ERROR, ... Socket option name constants for setsockopt() and getsockopt() at the C level. =head2 IP_OPTIONS, IP_TOS, IP_TTL, ... Socket option name constants for IPv4 socket options at the C level. =head2 IPTOS_LOWDELAY, IPTOS_THROUGHPUT, IPTOS_RELIABILITY, ... Socket option value constants for C socket option. =head2 MSG_BCAST, MSG_OOB, MSG_TRUNC, ... Message flag constants for send() and recv(). =head2 SHUT_RD, SHUT_RDWR, SHUT_WR Direction constants for shutdown(). =head2 INADDR_ANY, INADDR_BROADCAST, INADDR_LOOPBACK, INADDR_NONE Constants giving the special C addresses for wildcard, broadcast, local loopback, and invalid addresses. Normally equivalent to inet_aton('0.0.0.0'), inet_aton('255.255.255.255'), inet_aton('localhost') and inet_aton('255.255.255.255') respectively. =head2 IPPROTO_IP, IPPROTO_IPV6, IPPROTO_TCP, ... IP protocol constants to use as the third argument to socket(), the level argument to getsockopt() or setsockopt(), or the value of the C socket option. =head2 TCP_CORK, TCP_KEEPALIVE, TCP_NODELAY, ... Socket option name constants for TCP socket options at the C level. =head2 IN6ADDR_ANY, IN6ADDR_LOOPBACK Constants giving the special C addresses for wildcard and local loopback. Normally equivalent to inet_pton(AF_INET6, "::") and inet_pton(AF_INET6, "::1") respectively. =head2 IPV6_ADD_MEMBERSHIP, IPV6_MTU, IPV6_V6ONLY, ... Socket option name constants for IPv6 socket options at the C level. =cut # Still undocumented: SCM_*, SOMAXCONN, IOV_MAX, UIO_MAXIOV =head1 STRUCTURE MANIPULATORS The following functions convert between lists of Perl values and packed binary strings representing structures. =cut =head2 $family = sockaddr_family $sockaddr Takes a packed socket address (as returned by pack_sockaddr_in(), pack_sockaddr_un() or the perl builtin functions getsockname() and getpeername()). Returns the address family tag. This will be one of the C constants, such as C for a C addresses or C for a C. It can be used to figure out what unpack to use for a sockaddr of unknown type. =head2 $sockaddr = pack_sockaddr_in $port, $ip_address Takes two arguments, a port number and an opaque string (as returned by inet_aton(), or a v-string). Returns the C structure with those arguments packed in and C filled in. For Internet domain sockets, this structure is normally what you need for the arguments in bind(), connect(), and send(). =head2 ($port, $ip_address) = unpack_sockaddr_in $sockaddr Takes a C structure (as returned by pack_sockaddr_in(), getpeername() or recv()). Returns a list of two elements: the port and an opaque string representing the IP address (you can use inet_ntoa() to convert the address to the four-dotted numeric format). Will croak if the structure does not represent an C address. In scalar context will return just the IP address. =head2 $sockaddr = sockaddr_in $port, $ip_address =head2 ($port, $ip_address) = sockaddr_in $sockaddr A wrapper of pack_sockaddr_in() or unpack_sockaddr_in(). In list context, unpacks its argument and returns a list consisting of the port and IP address. In scalar context, packs its port and IP address arguments as a C and returns it. Provided largely for legacy compatibility; it is better to use pack_sockaddr_in() or unpack_sockaddr_in() explicitly. =head2 $sockaddr = pack_sockaddr_in6 $port, $ip6_address, [$scope_id, [$flowinfo]] Takes two to four arguments, a port number, an opaque string (as returned by inet_pton()), optionally a scope ID number, and optionally a flow label number. Returns the C structure with those arguments packed in and C filled in. IPv6 equivalent of pack_sockaddr_in(). =head2 ($port, $ip6_address, $scope_id, $flowinfo) = unpack_sockaddr_in6 $sockaddr Takes a C structure. Returns a list of four elements: the port number, an opaque string representing the IPv6 address, the scope ID, and the flow label. (You can use inet_ntop() to convert the address to the usual string format). Will croak if the structure does not represent an C address. In scalar context will return just the IP address. =head2 $sockaddr = sockaddr_in6 $port, $ip6_address, [$scope_id, [$flowinfo]] =head2 ($port, $ip6_address, $scope_id, $flowinfo) = sockaddr_in6 $sockaddr A wrapper of pack_sockaddr_in6() or unpack_sockaddr_in6(). In list context, unpacks its argument according to unpack_sockaddr_in6(). In scalar context, packs its arguments according to pack_sockaddr_in6(). Provided largely for legacy compatibility; it is better to use pack_sockaddr_in6() or unpack_sockaddr_in6() explicitly. =head2 $sockaddr = pack_sockaddr_un $path Takes one argument, a pathname. Returns the C structure with that path packed in with C filled in. For C sockets, this structure is normally what you need for the arguments in bind(), connect(), and send(). =head2 ($path) = unpack_sockaddr_un $sockaddr Takes a C structure (as returned by pack_sockaddr_un(), getpeername() or recv()). Returns a list of one element: the pathname. Will croak if the structure does not represent an C address. =head2 $sockaddr = sockaddr_un $path =head2 ($path) = sockaddr_un $sockaddr A wrapper of pack_sockaddr_un() or unpack_sockaddr_un(). In a list context, unpacks its argument and returns a list consisting of the pathname. In a scalar context, packs its pathname as a C and returns it. Provided largely for legacy compatibility; it is better to use pack_sockaddr_un() or unpack_sockaddr_un() explicitly. These are only supported if your system has EFE. =head2 $ip_mreq = pack_ip_mreq $multiaddr, $interface Takes an IPv4 multicast address and optionally an interface address (or C). Returns the C structure with those arguments packed in. Suitable for use with the C and C sockopts. =head2 ($multiaddr, $interface) = unpack_ip_mreq $ip_mreq Takes an C structure. Returns a list of two elements; the IPv4 multicast address and interface address. =head2 $ip_mreq_source = pack_ip_mreq_source $multiaddr, $source, $interface Takes an IPv4 multicast address, source address, and optionally an interface address (or C). Returns the C structure with those arguments packed in. Suitable for use with the C and C sockopts. =head2 ($multiaddr, $source, $interface) = unpack_ip_mreq_source $ip_mreq Takes an C structure. Returns a list of three elements; the IPv4 multicast address, source address and interface address. =head2 $ipv6_mreq = pack_ipv6_mreq $multiaddr6, $ifindex Takes an IPv6 multicast address and an interface number. Returns the C structure with those arguments packed in. Suitable for use with the C and C sockopts. =head2 ($multiaddr6, $ifindex) = unpack_ipv6_mreq $ipv6_mreq Takes an C structure. Returns a list of two elements; the IPv6 address and an interface number. =cut =head1 FUNCTIONS =cut =head2 $ip_address = inet_aton $string Takes a string giving the name of a host, or a textual representation of an IP address and translates that to an packed binary address structure suitable to pass to pack_sockaddr_in(). If passed a hostname that cannot be resolved, returns C. For multi-homed hosts (hosts with more than one address), the first address found is returned. For portability do not assume that the result of inet_aton() is 32 bits wide, in other words, that it would contain only the IPv4 address in network order. This IPv4-only function is provided largely for legacy reasons. Newly-written code should use getaddrinfo() or inet_pton() instead for IPv6 support. =head2 $string = inet_ntoa $ip_address Takes a packed binary address structure such as returned by unpack_sockaddr_in() (or a v-string representing the four octets of the IPv4 address in network order) and translates it into a string of the form C where the Cs are numbers less than 256 (the normal human-readable four dotted number notation for Internet addresses). This IPv4-only function is provided largely for legacy reasons. Newly-written code should use getnameinfo() or inet_ntop() instead for IPv6 support. =head2 $address = inet_pton $family, $string Takes an address family (such as C or C) and a string containing a textual representation of an address in that family and translates that to an packed binary address structure. See also getaddrinfo() for a more powerful and flexible function to look up socket addresses given hostnames or textual addresses. =head2 $string = inet_ntop $family, $address Takes an address family and a packed binary address structure and translates it into a human-readable textual representation of the address; typically in C form for C or C form for C. See also getnameinfo() for a more powerful and flexible function to turn socket addresses into human-readable textual representations. =head2 ($err, @result) = getaddrinfo $host, $service, [$hints] Given both a hostname and service name, this function attempts to resolve the host name into a list of network addresses, and the service name into a protocol and port number, and then returns a list of address structures suitable to connect() to it. Given just a host name, this function attempts to resolve it to a list of network addresses, and then returns a list of address structures giving these addresses. Given just a service name, this function attempts to resolve it to a protocol and port number, and then returns a list of address structures that represent it suitable to bind() to. This use should be combined with the C flag; see below. Given neither name, it generates an error. If present, $hints should be a reference to a hash, where the following keys are recognised: =over 4 =item flags => INT A bitfield containing C constants; see below. =item family => INT Restrict to only generating addresses in this address family =item socktype => INT Restrict to only generating addresses of this socket type =item protocol => INT Restrict to only generating addresses for this protocol =back The return value will be a list; the first value being an error indication, followed by a list of address structures (if no error occurred). The error value will be a dualvar; comparable to the C error constants, or printable as a human-readable error message string. If no error occurred it will be zero numerically and an empty string. Each value in the results list will be a hash reference containing the following fields: =over 4 =item family => INT The address family (e.g. C) =item socktype => INT The socket type (e.g. C) =item protocol => INT The protocol (e.g. C) =item addr => STRING The address in a packed string (such as would be returned by pack_sockaddr_in()) =item canonname => STRING The canonical name for the host if the C flag was provided, or C otherwise. This field will only be present on the first returned address. =back The following flag constants are recognised in the $hints hash. Other flag constants may exist as provided by the OS. =over 4 =item AI_PASSIVE Indicates that this resolution is for a local bind() for a passive (i.e. listening) socket, rather than an active (i.e. connecting) socket. =item AI_CANONNAME Indicates that the caller wishes the canonical hostname (C) field of the result to be filled in. =item AI_NUMERICHOST Indicates that the caller will pass a numeric address, rather than a hostname, and that getaddrinfo() must not perform a resolve operation on this name. This flag will prevent a possibly-slow network lookup operation, and instead return an error if a hostname is passed. =back =head2 ($err, $hostname, $servicename) = getnameinfo $sockaddr, [$flags, [$xflags]] Given a packed socket address (such as from getsockname(), getpeername(), or returned by getaddrinfo() in a C field), returns the hostname and symbolic service name it represents. $flags may be a bitmask of C constants, or defaults to 0 if unspecified. The return value will be a list; the first value being an error condition, followed by the hostname and service name. The error value will be a dualvar; comparable to the C error constants, or printable as a human-readable error message string. The host and service names will be plain strings. The following flag constants are recognised as $flags. Other flag constants may exist as provided by the OS. =over 4 =item NI_NUMERICHOST Requests that a human-readable string representation of the numeric address be returned directly, rather than performing a name resolve operation that may convert it into a hostname. This will also avoid potentially-blocking network IO. =item NI_NUMERICSERV Requests that the port number be returned directly as a number representation rather than performing a name resolve operation that may convert it into a service name. =item NI_NAMEREQD If a name resolve operation fails to provide a name, then this flag will cause getnameinfo() to indicate an error, rather than returning the numeric representation as a human-readable string. =item NI_DGRAM Indicates that the socket address relates to a C socket, for the services whose name differs between TCP and UDP protocols. =back The following constants may be supplied as $xflags. =over 4 =item NIx_NOHOST Indicates that the caller is not interested in the hostname of the result, so it does not have to be converted. C will be returned as the hostname. =item NIx_NOSERV Indicates that the caller is not interested in the service name of the result, so it does not have to be converted. C will be returned as the service name. =back =head1 getaddrinfo() / getnameinfo() ERROR CONSTANTS The following constants may be returned by getaddrinfo() or getnameinfo(). Others may be provided by the OS. =over 4 =item EAI_AGAIN A temporary failure occurred during name resolution. The operation may be successful if it is retried later. =item EAI_BADFLAGS The value of the C hint to getaddrinfo(), or the $flags parameter to getnameinfo() contains unrecognised flags. =item EAI_FAMILY The C hint to getaddrinfo(), or the family of the socket address passed to getnameinfo() is not supported. =item EAI_NODATA The host name supplied to getaddrinfo() did not provide any usable address data. =item EAI_NONAME The host name supplied to getaddrinfo() does not exist, or the address supplied to getnameinfo() is not associated with a host name and the C flag was supplied. =item EAI_SERVICE The service name supplied to getaddrinfo() is not available for the socket type given in the $hints. =back =cut =head1 EXAMPLES =head2 Lookup for connect() The getaddrinfo() function converts a hostname and a service name into a list of structures, each containing a potential way to connect() to the named service on the named host. use IO::Socket; use Socket qw(SOCK_STREAM getaddrinfo); my %hints = (socktype => SOCK_STREAM); my ($err, @res) = getaddrinfo("localhost", "echo", \%hints); die "Cannot getaddrinfo - $err" if $err; my $sock; foreach my $ai (@res) { my $candidate = IO::Socket->new(); $candidate->socket($ai->{family}, $ai->{socktype}, $ai->{protocol}) or next; $candidate->connect($ai->{addr}) or next; $sock = $candidate; last; } die "Cannot connect to localhost:echo" unless $sock; $sock->print("Hello, world!\n"); print <$sock>; Because a list of potential candidates is returned, the C loop tries each in turn until it finds one that succeeds both the socket() and connect() calls. This function performs the work of the legacy functions gethostbyname(), getservbyname(), inet_aton() and pack_sockaddr_in(). In practice this logic is better performed by L. =head2 Making a human-readable string out of an address The getnameinfo() function converts a socket address, such as returned by getsockname() or getpeername(), into a pair of human-readable strings representing the address and service name. use IO::Socket::IP; use Socket qw(getnameinfo); my $server = IO::Socket::IP->new(LocalPort => 12345, Listen => 1) or die "Cannot listen - $@"; my $socket = $server->accept or die "accept: $!"; my ($err, $hostname, $servicename) = getnameinfo($socket->peername); die "Cannot getnameinfo - $err" if $err; print "The peer is connected from $hostname\n"; Since in this example only the hostname was used, the redundant conversion of the port number into a service name may be omitted by passing the C flag. use Socket qw(getnameinfo NIx_NOSERV); my ($err, $hostname) = getnameinfo($socket->peername, 0, NIx_NOSERV); This function performs the work of the legacy functions unpack_sockaddr_in(), inet_ntoa(), gethostbyaddr() and getservbyport(). In practice this logic is better performed by L. =head2 Resolving hostnames into IP addresses To turn a hostname into a human-readable plain IP address use getaddrinfo() to turn the hostname into a list of socket structures, then getnameinfo() on each one to make it a readable IP address again. use Socket qw(:addrinfo SOCK_RAW); my ($err, @res) = getaddrinfo($hostname, "", {socktype => SOCK_RAW}); die "Cannot getaddrinfo - $err" if $err; while( my $ai = shift @res ) { my ($err, $ipaddr) = getnameinfo($ai->{addr}, NI_NUMERICHOST, NIx_NOSERV); die "Cannot getnameinfo - $err" if $err; print "$ipaddr\n"; } The C hint to getaddrinfo() filters the results to only include one socket type and protocol. Without this most OSes return three combinations, for C, C and C, resulting in triplicate output of addresses. The C flag to getnameinfo() causes it to return a string-formatted plain IP address, rather than reverse resolving it back into a hostname. This combination performs the work of the legacy functions gethostbyname() and inet_ntoa(). =head2 Accessing socket options The many C and other constants provide the socket option names for getsockopt() and setsockopt(). use IO::Socket::INET; use Socket qw(SOL_SOCKET SO_RCVBUF IPPROTO_IP IP_TTL); my $socket = IO::Socket::INET->new(LocalPort => 0, Proto => 'udp') or die "Cannot create socket: $@"; $socket->setsockopt(SOL_SOCKET, SO_RCVBUF, 64*1024) or die "setsockopt: $!"; print "Receive buffer is ", $socket->getsockopt(SOL_SOCKET, SO_RCVBUF), " bytes\n"; print "IP TTL is ", $socket->getsockopt(IPPROTO_IP, IP_TTL), "\n"; As a convenience, L's setsockopt() method will convert a number into a packed byte buffer, and getsockopt() will unpack a byte buffer of the correct size back into a number. =cut =head1 AUTHOR This module was originally maintained in Perl core by the Perl 5 Porters.

Preamble The license agreements of most software companies try to keep users at the mercy of those companies. By contrast, our General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. The General Public License applies to the Free Software Foundation's software and to any other program whose authors commit to using it. You can use it for your programs, too. When we speak of free software, we are referring to freedom, not price. Specifically, the General Public License is designed to make sure that you have the freedom to give away or sell copies of free software, that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of a such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must tell them their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any work containing the Program or a portion of it, either verbatim or with modifications. Each licensee is addressed as "you". 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this General Public License and to the absence of any warranty; and give any other recipients of the Program a copy of this General Public License along with the Program. You may charge a fee for the physical act of transferring a copy. 2. You may modify your copy or copies of the Program or any portion of it, and copy and distribute such modifications under the terms of Paragraph 1 above, provided that you also do the following: a) cause the modified files to carry prominent notices stating that you changed the files and the date of any change; and b) cause the whole of any work that you distribute or publish, that in whole or in part contains the Program or any part thereof, either with or without modifications, to be licensed at no charge to all third parties under the terms of this General Public License (except that you may choose to grant warranty protection to some or all third parties, at your option). c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the simplest and most usual way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this General Public License. d) You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. Mere aggregation of another independent work with the Program (or its derivative) on a volume of a storage or distribution medium does not bring the other work under the scope of these terms. 3. You may copy and distribute the Program (or a portion or derivative of it, under Paragraph 2) in object code or executable form under the terms of Paragraphs 1 and 2 above provided that you also do one of the following: a) accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Paragraphs 1 and 2 above; or, b) accompany it with a written offer, valid for at least three years, to give any third party free (except for a nominal charge for the cost of distribution) a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Paragraphs 1 and 2 above; or, c) accompany it with the information you received as to where the corresponding source code may be obtained. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form alone.) Source code for a work means the preferred form of the work for making modifications to it. For an executable file, complete source code means all the source code for all modules it contains; but, as a special exception, it need not include source code for modules which are standard libraries that accompany the operating system on which the executable file runs, or for standard header files or definitions files that accompany that operating system. 4. You may not copy, modify, sublicense, distribute or transfer the Program except as expressly provided under this General Public License. Any attempt otherwise to copy, modify, sublicense, distribute or transfer the Program is void, and will automatically terminate your rights to use the Program under this License. However, parties who have received copies, or rights to use copies, from you under this General Public License will not have their licenses terminated so long as such parties remain in full compliance. 5. By copying, distributing or modifying the Program (or any work based on the Program) you indicate your acceptance of this license to do so, and all its terms and conditions. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. 7. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of the license which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the license, you may choose any version ever published by the Free Software Foundation. 8. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS Appendix: How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to humanity, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) 19yy This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 1, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston MA 02110-1301 USA Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) 19xx name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type 'show w'. This is free software, and you are welcome to redistribute it under certain conditions; type 'show c' for details. The hypothetical commands 'show w' and 'show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than 'show w' and 'show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary.

Definitions: "Package" refers to the collection of files distributed by the Copyright Holder, and derivatives of that collection of files created through textual modification. "Standard Version" refers to such a Package if it has not been modified, or has been modified in accordance with the wishes of the Copyright Holder as specified below. "Copyright Holder" is whoever is named in the copyright or copyrights for the package. "You" is you, if you're thinking about copying or distributing this Package. "Reasonable copying fee" is whatever you can justify on the basis of media cost, duplication charges, time of people involved, and so on. (You will not be required to justify it to the Copyright Holder, but only to the computing community at large as a market that must bear the fee.) "Freely Available" means that no fee is charged for the item itself, though there may be fees involved in handling the item. It also means that recipients of the item may redistribute it under the same conditions they received it. 1. You may make and give away verbatim copies of the source form of the Standard Version of this Package without restriction, provided that you duplicate all of the original copyright notices and associated disclaimers. 2. You may apply bug fixes, portability fixes and other modifications derived from the Public Domain or from the Copyright Holder. A Package modified in such a way shall still be considered the Standard Version. 3. You may otherwise modify your copy of this Package in any way, provided that you insert a prominent notice in each changed file stating how and when you changed that file, and provided that you do at least ONE of the following: a) place your modifications in the Public Domain or otherwise make them Freely Available, such as by posting said modifications to Usenet or an equivalent medium, or placing the modifications on a major archive site such as uunet.uu.net, or by allowing the Copyright Holder to include your modifications in the Standard Version of the Package. b) use the modified Package only within your corporation or organization. c) rename any non-standard executables so the names do not conflict with standard executables, which must also be provided, and provide a separate manual page for each non-standard executable that clearly documents how it differs from the Standard Version. d) make other distribution arrangements with the Copyright Holder. 4. You may distribute the programs of this Package in object code or executable form, provided that you do at least ONE of the following: a) distribute a Standard Version of the executables and library files, together with instructions (in the manual page or equivalent) on where to get the Standard Version. b) accompany the distribution with the machine-readable source of the Package with your modifications. c) give non-standard executables non-standard names, and clearly document the differences in manual pages (or equivalent), together with instructions on where to get the Standard Version. d) make other distribution arrangements with the Copyright Holder. 5. You may charge a reasonable copying fee for any distribution of this Package. You may charge any fee you choose for support of this Package. You may not charge a fee for this Package itself. However, you may distribute this Package in aggregate with other (possibly commercial) programs as part of a larger (possibly commercial) software distribution provided that you do not advertise this Package as a product of your own. You may embed this Package's interpreter within an executable of yours (by linking); this shall be construed as a mere form of aggregation, provided that the complete Standard Version of the interpreter is so embedded. 6. The scripts and library files supplied as input to or produced as output from the programs of this Package do not automatically fall under the copyright of this Package, but belong to whoever generated them, and may be sold commercially, and may be aggregated with this Package. If such scripts or library files are aggregated with this Package via the so-called "undump" or "unexec" methods of producing a binary executable image, then distribution of such an image shall neither be construed as a distribution of this Package nor shall it fall under the restrictions of Paragraphs 3 and 4, provided that you do not represent such an executable image as a Standard Version of this Package. 7. C subroutines (or comparably compiled subroutines in other languages) supplied by you and linked into this Package in order to emulate subroutines and variables of the language defined by this Package shall not be considered part of this Package, but are the equivalent of input as in Paragraph 6, provided these subroutines do not change the language in any way that would cause it to fail the regression tests for the language. 8. Aggregation of this Package with a commercial distribution is always permitted provided that the use of this Package is embedded; that is, when no overt attempt is made to make this Package's interfaces visible to the end user of the commercial distribution. Such use shall not be construed as a distribution of this Package. 9.
