In the page of the manual:
function.ifxus-seek-slob.html

in the title are written:
ifxus_seek_slog

but just above "Description" are:
int ifxus_seek_blob (long bid, int mode, long offset)

and should be:
int ifxus_seek_slob (long bid, int mode, long offset)

The same occurs on pages:
function.pdf-open-ccitt.html
function.pdf-arcn.html
function.zip-entry-close.html

Finally, the name of the file:
   function.swf-shapelinesold.html
