find_allegro_resource(3alleg4)   Allegro manual   find_allegro_resource(3alleg4)

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

       #include <allegro.h>

       int find_allegro_resource(char *dest, const char *resource, const char
       *ext, const char *datafile, const char *objectname, const char *envvar,
       const char *subdir, int size);

       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. */

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