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.
