NAME¶
pack_ungetc - 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.

pack_getc(3alleg4),
pack_fgets(3alleg4)
