pack_ungetc - Man Page
Moves one single character back to the input buffer. Allegro game programming library.
Synopsis
#include <allegro.h>
int pack_ungetc(int c, PACKFILE *f);
Description
Puts a character back to the file's input buffer. Like with ungetc from libc, only a single push back is guaranteed.
Note: pack_fgets internally uses pack_ungetc, so never use pack_ungetc directly after using pack_fgets on a PACKFILE.
Return Value
Returns c on success, or EOF on error.
