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.
