NAME

       pack_fseek - Seeks inside a stream. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       int pack_fseek(PACKFILE *f, int offset);

DESCRIPTION

       Moves the position indicator of the stream `f'. Unlike the standard fseek() function, this
       only supports forward movements relative to the current position and in read-only streams,
       so  don't  use  negative  offsets.  Note that seeking is very slow when reading compressed
       files, and so should be avoided unless you are sure  that  the  file  is  not  compressed.
       Example:

          input_file = pack_fopen("data.bin", "r");
          if (!input_file)
             abort_on_error("Couldn't open binary data!");
          /* Skip some useless header before reading data. */
          pack_fseek(input_file, 32);

RETURN VALUE

       Returns zero on success or a negative number on error, storing the error code in `errno'.
