Check the implementation of the FPC CRT unit how a unit can hook into the write(ln) mechanisms: http://svn.freepascal.org/cgi-bin/viewvc.cgi/trunk/packages/rtl-console/src/unix/crt.pp?revision=26372&view=markup Have a look at AssignCrt and CrtOpen, how it is done. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
