pack_ungetc(3alleg4) | Allegro manual | pack_ungetc(3alleg4) |
pack_ungetc - Moves one single character back to the input buffer. Allegro game programming library.
#include <allegro.h>
int pack_ungetc(int c, PACKFILE *f);
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.
Returns c on success, or EOF on error.
