Hi, <br>
<br>
write your own small wrapper function with the third parameter which
translates relative positions to absolute positions. It is not so
difficult, just a little bit of math (and physfs_tell). The worst is
probably SEEK_END. If Physfs_uint64 is a problem for you, try a weak
& dynamic typed language.<br>
