A copy of the license is included in the ``GNU Free @c Documentation License'' file as part of this distribution. Gnulib has two modules for retrieving the name of the currently executing program: @code{progname} and @code{getprogname}. @findex progname @vindex program_name The @code{progname} module defines a variable @code{program_name}. It contains the name of the currently executing program, on all platforms. But it cannot be used implicitly: It requires that every @code{main} function be modified to invoke @code{set_program_name (argv[0])} as one of its first actions. @findex getprogname The @code{getprogname} module defines a function @code{getprogname()}. It returns the name of the currently executing program, on most platforms. The advantage of this module is that it can be used without prior initializations. But it has limitations: In some rare situations, it cannot determine the name; then it returns @code{"?"} instead. And on some platforms, it returns a truncated program name. @findex error The @code{error} function uses the @code{getprogname} module.
