NAME

       al_findfirst - Low-level function for searching files. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       int al_findfirst(const char *pattern, struct al_ffblk *info, int attrib);

DESCRIPTION

       Low-level  function  for  searching  files.  This  function  finds the first file which matches the given
       wildcard specification and file attributes (see above). The information about the file (if any)  will  be
       put in the al_ffblk structure which you have to provide. The al_ffblk structure looks like:

          struct al_ffblk
          {
             int attrib;       - actual attributes of the file found
             time_t time;      - modification time of file
             char name[512];   - name of file
          };

       There is some other stuff in the structure as well, but it is there for internal use only. Example:

          struct al_ffblk info;

          if (al_findfirst("*.pcx", &info, FA_ALL) != 0) {
             /* Tell user there are no PCX files. */
             return;
          }

RETURN VALUE

       The  function returns non-zero if no match is found or if an error occurred and, in the latter case, sets
       `errno' accordingly. It returns zero if a match is found, allocating some memory for internal use in  the
       structure.   Therefore  you have to close your search when you are finished to avoid memory leaks in your
       program.
