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);
