I wrote them a few years back for mozilla and they were part of the port. Don't know what happened in the meantime, because since alpha support is removed I stopped spending time into it. The whole xptcinvoke thing is completely breandead anyway. The intention was to have a portable interfacing to modules, but in fact they just read the C++ vtable using assembly, which the compiler can do without any help. The assembly calling functions need to know the compiler specific vtable and not a fixed self defined, which is not what I expected to see. It took me several days to understand that they want something senseless. -- B.Walter <bernd@bwct.de> http://www.bwct.de Modbus/TCP Ethernet I/O Baugruppen, ARM basierte FreeBSD Rechner uvm.
