14 The zzip_seek function will perform a lseek(2) operation on a
15 real/zipped file
16
17 It will try to seek to the offset specified by offset, relative to
18 whence, which is one of SEEK_SET, SEEK_CUR or SEEK_END.
19
20 If the file-handle is wrapping a stat'able file then it will actually
21 just perform a normal lseek(2)-call. Otherwise the relative offset is
22 calculated, negative offsets are transformed into positive ones by
23 rewinding the file, and then data is read until the offset is reached.
24 This can make the function terribly slow, but this is how gzio
25 implements it, so I'm not sure there is a better way without using the
26 internals of the algorithm.
