pack_ungetc (3) - Linux Manuals

pack_ungetc: Moves one single character back to the input buffer. Allegro game programming library.

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.
