Subject: [Caml-list] Unix.lseek versus Pervasives.pos

Currently I am trying to handle "LargeFiles" while marshalling caml 
values and I have run into this incidental problem (nothing to do with 
LargeFile). If I open a file with "open_out_bin", write to it using 
"output_value" and then try to determine the position in the file using 
"pos", I get the correct value. However, if I use Unix.lseek thus

Unix.lseek (Unix.descr_of_out_channel fd_out) 0 Unix.SEEK_CUR

I get a different value (so far always 0) than the one I get from

pos fd_out

The manual does not seem to help. Any advice will be appreciated.
