NAME

       zzip_seek, zzip_seek32 -  seek.

SYNOPSIS

       #include <zzip/lib.h>

       zzip_off_t
       zzip_seek(ZZIP_FILE * fp, zzip_off_t offset, int whence)

       long
       zzip_seek32(ZZIP_FILE * fp, long offset, int whence)

DESCRIPTION

        The zzip_seek function will perform a lseek(2) operation on a real/zipped file

        It will try to seek to the offset specified by offset, relative to whence, which is one
       of SEEK_SET, SEEK_CUR or SEEK_END.

        If the file-handle is wrapping a stat'able file then it will actually just perform a
       normal lseek(2)-call. Otherwise the relative offset is calculated, negative offsets are
       transformed into positive ones by rewinding the file, and then data is read until the
       offset is reached. This can make the function terribly slow, but this is how gzio
       implements it, so I'm not sure there is a better way without using the internals of the
       algorithm.

        The zzip_seek32 function is provided for users who can not use any largefile-mode.
