find_allegro_resource - Searches for a support file in many places. Allegro game programming library.

       Searches for a support file, eg. `allegro.cfg' or `language.dat'. Passed  a  resource  string  describing
       what  you  are  looking  for,  along  with extra optional information such as the default extension, what
       datafile to look inside, what the datafile object name is likely to be, any special environment  variable
       to  check,  and  any  subdirectory  that  you  would  like to check as well as the default location, this
       function looks in a hell of a lot of different places :-). Pass NULL  for  the  parameters  you  are  not
       using.

       Check  the  documentation  chapter  specific  to  your  platform for information on additional paths this
       function might search for. Also, don't forget about set_allegro_resource_path() to extend  the  searches.
       Example:

          char path[256];
          int ret;
          ret = find_allegro_resource(path, "scores.cfg", NULL, NULL,
                                      NULL, NULL, NULL, sizeof(path));
          if (ret == 0) {
             /* Found system wide scores file. */
          } else {
             /* No previous scores, create our own file. */
          }

       find_allegro_resource - Searches for a support file in many places. Allegro game programming library.

       Returns zero on success, and stores a full path to the file (at most size bytes) into the dest buffer.
