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

DESCRIPTION

18       Searches for a  support  file,  eg.  `allegro.cfg'  or  `language.dat'.
19       Passed  a  resource  string  describing what you are looking for, along
20       with extra optional information such as  the  default  extension,  what
21       datafile to look inside, what the datafile object name is likely to be,
22       any special environment variable to check, and  any  subdirectory  that
23       you  would like to check as well as the default location, this function
24       looks in a hell of a lot of different places :-).  Pass  NULL  for  the
25       parameters you are not using.
26
27       Check  the documentation chapter specific to your platform for informa‐
28       tion on additional paths this function might search  for.  Also,  don't
29       forget  about set_allegro_resource_path() to extend the searches. Exam‐
30       ple:
31
32          char path[256];
33          int ret;
34          ret = find_allegro_resource(path, "scores.cfg", NULL, NULL,
35                                      NULL, NULL, NULL, sizeof(path));
36          if (ret == 0) {
37             /* Found system wide scores file. */
38          } else {
39             /* No previous scores, create our own file. */
40          }
41

RETURN VALUE

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