pack_ungetc(3)                  Allegro manual                  pack_ungetc(3)

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.

SEE ALSO
       pack_getc(3), pack_fgets(3)
