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

       #include <allegro.h>

       void get_executable_name(char *buf, int size);

       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);
