That should work fine.

It means that the .DLL expects to receive a 32 bit integer from VFP (VFP will massage your parameter to that form) and the name is just an arbitrary string - I actually take the argument from the MSDN and use it there as a cue to what the DLL expects to receive, but the actual name uExitCode is arbitrary and unneeded.
