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.
