I am using gameME 5.0.0 and it registers forwards.
A parameter is Handle.

It says datapack is an invalid handle even if it is not equal to INVALID_HANDLE and as is above it returned a number like ac7e. I tried changing to Call_PushCell (without Ref) and then it showed a number like 23fa14cc, still invalid handle but not equal to INVALID_HANDLE. I have tried adding _: into the front of pack but didn't help either.

How can I safely pass a DataPack (Handle) through a registered forward?

It would help if you posted the actual error message, which includes an error code detailing why the handle is considered invalid.

You have to be the owner of the Datapack handle to read or write from it.

Handles should generally not be passed by-ref, as they are references internally.

Error code 4 (as is) and 5 (with Call_PushCell).

[SM] Exception reported: Handle 75b8 cannot be cloned because it is invalid (error 4)

I see now, thanks. Anyways, this is not some kind of good bie, if you still have stuff to add, please do so.

Error 4 means the handle is actually invalid - rather than being free'd already - and due to the value it looks like it's probably a mix up between references (make sure the call mode matches the prototype in the function). Error 5 is access restrictions and probably due to the lack of a clone.

Well as is, gameME 5.0.0 uses Call_PushCellRef(Handle hPack) and its INC clearly specifies Handle hPack rather than Handle & hPack.

So when I changed Call_PushCellRef to Call_PushCell I have somehow partially fixed it and the error code changed from 4 to 5 (which is OK from what you stated above, access restrictions).

Don't worry, I will mark this thread as solved and again, thanks, I know what I have to do now to get my stuff working (I will add new forward parameters of type int, float and const char[]), I just didn't understand what was going on. Also thought it might be easily fixed, globally (inside gameME 5.0.0).
