In other projects, it is set to # '$srcdir', '$srcdir/..', or '$srcdir/../..'. # # Of course, Automake must honor this variable whenever it calls a # tool from the auxiliary directory. The problem is that $srcdir (and # therefore $ac_aux_dir as well) can be either absolute or relative, # depending on how configure is run. This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is '.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir.

Copying and distribution of this file, with or without modification, are permitted in any medium without royalty provided the copyright notice and this notice are preserved. This file is offered as-is, without warranty of any kind. Basic Installation ================== Briefly, the shell command './configure && make && make install' should configure, build, and install this package. The following more-detailed instructions are generic; see the 'README' file for instructions specific to this package. Some packages provide this 'INSTALL' file but do not implement all of the features documented below. The lack of an optional feature in a given package is not necessarily a bug. More recommendations for GNU packages can be found in *note Makefile Conventions: (standards)Makefile Conventions. The 'configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a 'Makefile' in each directory of the package. It may also create one or more '.h' files containing system-dependent definitions. Finally, it creates a shell script 'config.status' that you can run in the future to recreate the current configuration, and a file 'config.log' containing compiler output (useful mainly for debugging 'configure'). It can also use an optional file (typically called 'config.cache' and enabled with '--cache-file=config.cache' or simply '-C') that saves the results of its tests to speed up reconfiguring. Caching is disabled by default to prevent problems with accidental use of stale cache files. If you need to do unusual things to compile the package, please try to figure out how 'configure' could check whether to do them, and mail diffs or instructions to the address given in the 'README' so they can be considered for the next release. If you are using the cache, and at some point 'config.cache' contains results you don't want to keep, you may remove or edit it. The file 'configure.ac' (or 'configure.in') is used to create 'configure' by a program called 'autoconf'. You need 'configure.ac' if you want to change it or regenerate 'configure' using a newer version of 'autoconf'. The simplest way to compile this package is: 1. 'cd' to the directory containing the package's source code and type './configure' to configure the package for your system. Running 'configure' might take a while. While running, it prints some messages telling which features it is checking for. 2. Type 'make' to compile the package. 3. Optionally, type 'make check' to run any self-tests that come with the package, generally using the just-built uninstalled binaries. 4. Type 'make install' to install the programs and any data files and documentation. When installing into a prefix owned by root, it is recommended that the package be configured and built as a regular user, and only the 'make install' phase executed with root privileges. 5. Optionally, type 'make installcheck' to repeat any self-tests, but this time using the binaries in their final installed location. This target does not install anything. Running this target as a regular user, particularly if the prior 'make install' required root privileges, verifies that the installation completed correctly. 6. You can remove the program binaries and object files from the source code directory by typing 'make clean'. To also remove the files that 'configure' created (so you can compile the package for a different kind of computer), type 'make distclean'. There is also a 'make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. 7. Often, you can also type 'make uninstall' to remove the installed files again. In practice, not all packages have tested that uninstallation works correctly, even though it is required by the GNU Coding Standards. 8. Some packages, particularly those that use Automake, provide 'make distcheck', which can by used by developers to test that all other targets like 'make install' and 'make uninstall' work correctly. This target is generally not run by end users. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the 'configure' script does not know about. Run './configure --help' for details on some of the pertinent environment variables. You can give 'configure' initial values for configuration parameters by setting variables in the command line or in the environment. Here is an example: ./configure CC=c99 CFLAGS=-g LIBS=-lposix *Note Defining Variables::, for more details. Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you can use GNU 'make'. 'cd' to the directory where you want the object files and executables to go and run the 'configure' script. 'configure' automatically checks for the source code in the directory that 'configure' is in and in '..'. This is known as a "VPATH" build. With a non-GNU 'make', it is safer to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use 'make distclean' before reconfiguring for another architecture. On MacOS X 10.5 and later systems, you can create libraries and executables that work on multiple system types--known as "fat" or "universal" binaries--by specifying multiple '-arch' options to the compiler but only a single '-arch' option to the preprocessor. Like this: ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CPP="gcc -E" CXXCPP="g++ -E" This is not guaranteed to produce working output in all cases, you may have to build one architecture at a time and combine the results using the 'lipo' tool if you have problems. Installation Names ================== By default, 'make install' installs the package's commands under '/usr/local/bin', include files under '/usr/local/include', etc. You can specify an installation prefix other than '/usr/local' by giving 'configure' the option '--prefix=PREFIX', where PREFIX must be an absolute file name. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you pass the option '--exec-prefix=PREFIX' to 'configure', the package uses PREFIX as the prefix for installing programs and libraries. Documentation and other data files still use the regular prefix. In addition, if you use an unusual directory layout you can give options like '--bindir=DIR' to specify different values for particular kinds of files. Run 'configure --help' for a list of the directories you can set and what kinds of files go in them. In general, the default for these options is expressed in terms of '${prefix}', so that specifying just '--prefix' will affect all of the other directory specifications that were not explicitly provided. The most portable way to affect installation locations is to pass the correct locations to 'configure'; however, many packages provide one or both of the following shortcuts of passing variable assignments to the 'make install' command line to change installation locations without having to reconfigure or recompile. The first method involves providing an override variable for each affected directory. For example, 'make install prefix=/alternate/directory' will choose an alternate location for all directory configuration variables that were expressed in terms of '${prefix}'. Any directories that were specified during 'configure', but not in terms of '${prefix}', must each be overridden at install time for the entire installation to be relocated. The approach of makefile variable overrides for each directory variable is required by the GNU Coding Standards, and ideally causes no recompilation. However, some platforms have known limitations with the semantics of shared libraries that end up requiring recompilation when using this method, particularly noticeable in packages that use GNU Libtool. The second method involves providing the 'DESTDIR' variable. For example, 'make install DESTDIR=/alternate/directory' will prepend '/alternate/directory' before all installation names. The approach of 'DESTDIR' overrides is not required by the GNU Coding Standards, and does not work on platforms that have drive letters. On the other hand, it does better at avoiding recompilation issues, and works well even when some directory options were not specified in terms of '${prefix}' at 'configure' time. Optional Features ================= If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving 'configure' the option '--program-prefix=PREFIX' or '--program-suffix=SUFFIX'. Some packages pay attention to '--enable-FEATURE' options to 'configure', where FEATURE indicates an optional part of the package. They may also pay attention to '--with-PACKAGE' options, where PACKAGE is something like 'gnu-as' or 'x' (for the X Window System). The 'README' should mention any '--enable-' and '--with-' options that the package recognizes. For packages that use the X Window System, 'configure' can usually find the X include and library files automatically, but if it doesn't, you can use the 'configure' options '--x-includes=DIR' and '--x-libraries=DIR' to specify their locations. Some packages offer the ability to configure how verbose the execution of 'make' will be. For these packages, running './configure --enable-silent-rules' sets the default to minimal output, which can be overridden with 'make V=1'; while running './configure --disable-silent-rules' sets the default to verbose, which can be overridden with 'make V=0'. Particular systems ================== On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC is not installed, it is recommended to use the following options in order to use an ANSI C compiler: ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" and if that doesn't work, install pre-built binaries of GCC for HP-UX. HP-UX 'make' updates targets which have the same timestamps as their prerequisites, which makes it generally unusable when shipped generated files such as 'configure' are involved. Use GNU 'make' instead. On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot parse its '' header file. The option '-nodtk' can be used as a workaround. If GNU CC is not installed, it is therefore recommended to try ./configure CC="cc" and if that doesn't work, try ./configure CC="cc -nodtk" On Solaris, don't put '/usr/ucb' early in your 'PATH'. This directory contains several dysfunctional programs; working variants of these programs are available in '/usr/bin'. So, if you need '/usr/ucb' in your 'PATH', put it _after_ '/usr/bin'. On Haiku, software installed for all users goes in '/boot/common', not '/usr/local'. It is recommended to use the following options: ./configure --prefix=/boot/common Specifying the System Type ========================== There may be some features 'configure' cannot figure out automatically, but needs to determine by the type of machine the package will run on. Usually, assuming the package is built to be run on the _same_ architectures, 'configure' can figure that out, but if it prints a message saying it cannot guess the machine type, give it the '--build=TYPE' option. TYPE can either be a short name for the system type, such as 'sun4', or a canonical name which has the form: CPU-COMPANY-SYSTEM where SYSTEM can have one of these forms: OS KERNEL-OS See the file 'config.sub' for the possible values of each field. If 'config.sub' isn't included in this package, then this package doesn't need to know the machine type. If you are _building_ compiler tools for cross-compiling, you should use the option '--target=TYPE' to select the type of system they will produce code for. If you want to _use_ a cross compiler, that generates code for a platform different from the build platform, you should specify the "host" platform (i.e., that on which the generated programs will eventually be run) with '--host=TYPE'. Sharing Defaults ================ If you want to set default values for 'configure' scripts to share, you can create a site shell script called 'config.site' that gives default values for variables like 'CC', 'cache_file', and 'prefix'. 'configure' looks for 'PREFIX/share/config.site' if it exists, then 'PREFIX/etc/config.site' if it exists. Or, you can set the 'CONFIG_SITE' environment variable to the location of the site script. A warning: not all 'configure' scripts look for a site script. Defining Variables ================== Variables not defined in a site shell script can be set in the environment passed to 'configure'. However, some packages may run configure again during the build, and the customized values of these variables may be lost. In order to avoid this problem, you should set them in the 'configure' command line, using 'VAR=value'. For example: ./configure CC=/usr/local2/bin/gcc causes the specified 'gcc' to be used as the C compiler (unless it is overridden in the site shell script). Unfortunately, this technique does not work for 'CONFIG_SHELL' due to an Autoconf limitation. Until the limitation is lifted, you can use this workaround: CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash 'configure' Invocation ====================== 'configure' recognizes the following options to control how it operates. '--help' '-h' Print a summary of all of the options to 'configure', and exit. '--help=short' '--help=recursive' Print a summary of the options unique to this package's 'configure', and exit. The 'short' variant lists options used only in the top level, while the 'recursive' variant lists options also present in any nested packages. '--version' '-V' Print the version of Autoconf used to generate the 'configure' script, and exit. '--cache-file=FILE' Enable the cache: use and save the results of the tests in FILE, traditionally 'config.cache'. FILE defaults to '/dev/null' to disable caching. '--config-cache' '-C' Alias for '--cache-file=config.cache'. '--quiet' '--silent' '-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to '/dev/null' (any error messages will still be shown). '--srcdir=DIR' Look for the package's source code in directory DIR. Usually 'configure' can determine that directory automatically. '--prefix=DIR' Use DIR as the installation prefix. *note Installation Names:: for more details, including other options available for fine-tuning the installation locations. '--no-create' '-n' Run the configure checks, but stop before creating any output files. 'configure' also accepts some other, not widely useful, options. Run 'configure --help' for more details. libserialport-0.1.2/AUTHORS0000644000175000001440000000220714702725614011123 ------------------------------------------------------------------------------- AUTHORS ------------------------------------------------------------------------------- Martin Ling conceived the idea for the library, designed the API and wrote much of the implementation and documentation.

By writing your serial code to use libserialport, you enable it to work transparently on any platform supported by the library. The operations that are supported are: - Port enumeration (obtaining a list of serial ports on the system). - Obtaining port metadata (USB device information, Bluetooth address, etc). - Opening and closing ports. - Setting port parameters (baud rate, parity, etc). - Reading, writing and flushing data. - Obtaining error information. libserialport is an open source project released under the LGPL3+ license. Status ====== The library should build and work on any Windows or Unix-based system. If it does not, please submit a bug. Enumeration is currently implemented on Windows, Mac OS X, FreeBSD and Linux. On other systems enumeration is not supported, but ports can still be opened by name and then used. If you know how to enumerate available ports on another OS, please submit a bug with this information, or better still a patch implementing it. Dependencies ============ No other libraries are required. Building ======== On Windows, libserialport can be built with Visual Studio 2019 or with the standalone MSBuild tool, using the solution and project files provided. For other environments, the package uses a GNU style build based on autotools. Run "./autogen.sh" to generate the build system, "./configure" to setup, then "make" to build the library and "make install" to install it. Windows builds can also be created using the autotools build system, using the MinGW-w64 toolchain from http://mingw-w64.sourceforge.net/ - either natively in Windows with the MSYS2 environment, or cross-compiling from another system. To build from MSYS2, the following packages must be installed: autoconf, automake-wrapper, libtool, make, and either mingw-w64-i686-gcc (for 32-bit) or mingw-w64-x86_64-gcc (for 64-bit). Open either the "MSYS2 MinGW 32-bit" or "MSYS2 MinGW 64-bit" command window from the Start menu and use this when configuring and building the package. Using the "MSYS2 MSYS" shell will build against the Cygwin compatibility layer; this works, but port enumeration and metadata will not be available, and binaries will depend on Cygwin. The builds produced by MinGW-w64 are normal Windows DLLs without additional dependencies. API === Doxygen API documentation is included.

If a terminal is connected to the first serial port * (COM1), use /dev/ttyu0 to refer to the terminal. If the terminal is on * the second serial port (COM2), use /dev/ttyu1, and so forth. * Generally, the call-in port is used for terminals. Call-in ports require * that the serial line assert the "Data Carrier Detect" signal to work * correctly. * * 2) Call-out ports are named /dev/cuauN on FreeBSD versions 10.x and higher * and /dev/cuadN on FreeBSD versions 9.x and lower. Call-out ports are * usually not used for terminals, but are used for modems. The call-out * port can be used if the serial cable or the terminal does not support * the "Data Carrier Detect" signal. * * FreeBSD also provides initialization devices (/dev/ttyuN.init and * /dev/cuauN.init or /dev/cuadN.init) and locking devices (/dev/ttyuN.lock * and /dev/cuauN.lock or /dev/cuadN.lock). The initialization devices are * used to initialize communications port parameters each time a port is * opened, such as crtscts for modems which use RTS/CTS signaling for flow * control. The locking devices are used to lock flags on ports to prevent * users or programs changing certain parameters. * * In line with the above device naming USB-serial devices have * the following naming: * * 1) call-in ports: /dev/ttyUN where N is the port number * 2) call-out ports: /dev/cuaUN where N is the port number * * See also: ucom(4), https://www.freebsd.org/cgi/man.cgi?query=ucom * * Getting USB serial port device description: * * In order to query USB serial ports for device description - the mapping * between the kernel device driver instances must be correlated with the * above mentioned device nodes. * * 1) For each USB-serial port (/dev/cuaUN) use libusb to lookup the device * description and the name of the kernel device driver instance. * 2) Query sysctl for the kernel device driver instance info. * 3) Derive the ttyname and (serial) port count for the kernel device * driver instance. * 4) If sysctl ttyname and port matches /dev/cuaUN apply the libusb * device description. */ #include #include #include #include #include #include #include #include #include #include #include #include #include "libserialport.h" #include "libserialport_internal.h" #define DEV_CUA_PATH "/dev/cua" //#define DBG(...) printf(__VA_ARGS__) #define DBG(...) static char *strrspn(const char *s, const char *charset) { char *t = (char *)s + strlen(s);

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. This version of the GNU Lesser General Public License incorporates the terms and conditions of version 3 of the GNU General Public License, supplemented by the additional permissions listed below. 0. Additional Definitions. As used herein, "this License" refers to version 3 of the GNU Lesser General Public License, and the "GNU GPL" refers to version 3 of the GNU General Public License. "The Library" refers to a covered work governed by this License, other than an Application or a Combined Work as defined below. An "Application" is any work that makes use of an interface provided by the Library, but which is not otherwise based on the Library. Defining a subclass of a class defined by the Library is deemed a mode of using an interface provided by the Library. A "Combined Work" is a work produced by combining or linking an Application with the Library. The particular version of the Library with which the Combined Work was made is also called the "Linked Version". The "Minimal Corresponding Source" for a Combined Work means the Corresponding Source for the Combined Work, excluding any source code for portions of the Combined Work that, considered in isolation, are based on the Application, and not on the Linked Version. The "Corresponding Application Code" for a Combined Work means the object code and/or source code for the Application, including any data and utility programs needed for reproducing the Combined Work from the Application, but excluding the System Libraries of the Combined Work. 1. Exception to Section 3 of the GNU GPL. You may convey a covered work under sections 3 and 4 of this License without being bound by section 3 of the GNU GPL. 2. Conveying Modified Versions. If you modify a copy of the Library, and, in your modifications, a facility refers to a function or data to be supplied by an Application that uses the facility (other than as an argument passed when the facility is invoked), then you may convey a copy of the modified version: a) under this License, provided that you make a good faith effort to ensure that, in the event an Application does not supply the function or data, the facility still operates, and performs whatever part of its purpose remains meaningful, or b) under the GNU GPL, with none of the additional permissions of this License applicable to that copy. 3. Object Code Incorporating Material from Library Header Files. The object code form of an Application may incorporate material from a header file that is part of the Library. You may convey such object code under terms of your choice, provided that, if the incorporated material is not limited to numerical parameters, data structure layouts and accessors, or small macros, inline functions and templates (ten or fewer lines in length), you do both of the following: a) Give prominent notice with each copy of the object code that the Library is used in it and that the Library and its use are covered by this License. b) Accompany the object code with a copy of the GNU GPL and this license document. 4. Combined Works. You may convey a Combined Work under terms of your choice that, taken together, effectively do not restrict modification of the portions of the Library contained in the Combined Work and reverse engineering for debugging such modifications, if you also do each of the following: a) Give prominent notice with each copy of the Combined Work that the Library is used in it and that the Library and its use are covered by this License. b) Accompany the Combined Work with a copy of the GNU GPL and this license document. c) For a Combined Work that displays copyright notices during execution, include the copyright notice for the Library among these notices, as well as a reference directing the user to the copies of the GNU GPL and this license document. d) Do one of the following: 0) Convey the Minimal Corresponding Source under the terms of this License, and the Corresponding Application Code in a form suitable for, and under terms that permit, the user to recombine or relink the Application with a modified version of the Linked Version to produce a modified Combined Work, in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source. 1) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (a) uses at run time a copy of the Library already present on the user's computer system, and (b) will operate properly with a modified version of the Library that is interface-compatible with the Linked Version. e) Provide Installation Information, but only if you would otherwise be required to provide such information under section 6 of the GNU GPL, and only to the extent that such information is necessary to install and execute a modified version of the Combined Work produced by recombining or relinking the Application with a modified version of the Linked Version. (If you use option 4d0, the Installation Information must accompany the Minimal Corresponding Source and Corresponding Application Code. If you use option 4d1, you must provide the Installation Information in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source.) 5. Combined Libraries. You may place library facilities that are a work based on the Library side by side in a single library together with other library facilities that are not Applications and are not covered by this License, and convey such a combined library under terms of your choice, if you do both of the following: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities, conveyed under the terms of this License. b) Give prominent notice with the combined library that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 6. Revised Versions of the GNU Lesser General Public License. The Free Software Foundation may publish revised and/or new versions of the GNU Lesser 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 Library as you received it specifies that a certain numbered version of the GNU Lesser General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that published version or of any later version published by the Free Software Foundation. If the Library as you received it does not specify a version number of the GNU Lesser General Public License, you may choose any version of the GNU Lesser General Public License ever published by the Free Software Foundation. If the Library as you received it specifies that a proxy can decide whether future versions of the GNU Lesser General Public License shall apply, that proxy's public statement of acceptance of any version is permanent authorization for you to choose that version for the Library. libserialport-0.1.2/examples/0000755000175000001440000000000014702741001011734 5libserialport-0.1.2/examples/port_config.c0000644000175000001440000001337114116754013014344 #include #include #include /* Example of how to configure a serial port. * * This example file is released to the public domain. */ /* Helper function for error handling. */ int check(enum sp_return result); /* Helper function to give a name for each parity mode. */ const char *parity_name(enum sp_parity parity); int main(int argc, char **argv) { /* Get the port name from the command line. */ if (argc != 2) { printf("Usage: %s \n", argv[0]); return -1; } char *port_name = argv[1]; /* A pointer to a struct sp_port, which will refer to * the port found. */ struct sp_port *port; printf("Looking for port %s.\n", port_name); /* Call sp_get_port_by_name() to find the port.

The examples currently included are: list_ports.c - displays a list of ports on the system. port_info.c - displays info about a particular port on the system. port_config.c - sets and displays configuration settings on a port. send_receive.c - loopback test sending & receiving data on 1 or 2 ports. await_events.c - awaits receive events on multiple ports simultaneously. handle_errors.c - demonstrates handling errors returned from the library. The programs themselves are completely OS-independent, and require only a C compiler and libserialport. The 'examples.sln' file is a solution file for Microsoft Visual Studio 2019 which will build libserialport and all of the example programs. The Makefile in this directory will attempt to build all the examples, using 'gcc' to compile them and 'pkg-config' to discover the include paths and linker settings needed to build with libserialport. It provides a minimal example of how to write a Makefile to build a program using libserialport. If you have make, gcc, pkg-config and libserialport installed correctly then running 'make' should build the example programs in this directory. If this doesn't work, you may need to modify the Makefile or set necessary paths in your environment to suit your system. You can also build these examples using any other compiler, IDE or build system. You just need the libserialport.h header available to compile them, and the libserialport library available to link and run them. These example files are hereby released into the public domain by the author. libserialport-0.1.2/examples/handle_errors.c0000644000175000001440000000742014116754013014660 #include #include #include /* Example of how to handle errors from libserialport. * * This example file is released to the public domain. */ /* Pointers used in the program to resources that may need to be freed. */ struct sp_port **port_list = NULL; struct sp_port_config *config = NULL; struct sp_port *port = NULL; /* Example of a function to clean up and exit the program with a given return code. */ void end_program(int return_code) { /* Free any structures we allocated. */ if (port_list != NULL) sp_free_port_list(port_list); if (config != NULL) sp_free_config(config); if (port != NULL) sp_free_port(port); /* Exit with the given return code. */ exit(return_code); } /* Example of a helper function for error handling. */ int check(enum sp_return result) { int error_code; char *error_message; switch (result) { /* Handle each of the four negative error codes that can be returned. * * In this example, we will end the program on any error, using * a different return code for each possible class of error. */ case SP_ERR_ARG: /* When SP_ERR_ARG is returned, there was a problem with one * or more of the arguments passed to the function, e.g. a null * pointer or an invalid value.

In the later case the parser # tries to guess whether the code is fixed or free formatted code, this is the # default for Fortran type files), VHDL, tcl.

AUTOLINK_SUPPORT = YES # If you use STL classes (i.e. std::string, std::vector, etc.) but do not want # to include (a tag file for) the STL sources as input, then you should set this # tag to YES in order to let doxygen match functions declarations and # definitions whose arguments contain STL classes (e.g. func(std::string); # versus func(std::string) {}).
