get_executable_name(3)          Allegro manual          get_executable_name(3)

NAME
       get_executable_name - Obtains the full path to the current executable.
       Allegro game programming library.

SYNOPSIS
       #include <allegro.h>

       void get_executable_name(char *buf, int size);

DESCRIPTION
       Fills `buf' with the full path to the current executable, writing at
       most `size' bytes.  This generally comes from `argv[0]' but on Unix
       systems it tries to get the information from the `/proc' filesystem
       first, searching the directories specified in `$PATH' if necessary. If
       this fails too, it tries to find the executable name from the output of
       the `ps' command, using `argv[0]' only as a last resort if all other
       options fail. Example:

          char name[200];
          ...
          get_executable_name(name, sizeof(name));
          allegro_message("Running `%s'\n", name);
