al_findfirst
al_findfirst(3alleg4) Allegro manual al_findfirst(3alleg4)
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.
