I hook a custom virtual function in two extensions:
CBaseEntity* CreateEntityByName(const char * className);

So that control is passed to B function of extension B, then to A from extension A then back to the original CreateEntityByName. It works fine if I use RETURN_META_VALUE_MNEWPARAMS in both A and B. I get this sequence:

O -> B -> A -> CreateEntityByName -> back to O

But I need to know the result CBaseEntity pointer in both A and B. So I replace the RETURN_META_VALUE_MNEWPARAMS with:

SH_CALL and RETURN_META_VALUE(MRES_SUPERCEDE , false);

The problem here is that SH_CALL bypasses both hooks and the original CreateEntityByName is called twice, so 2 entities are created. I get this sequence:

O -> B, SH_CALL-> CreateEntityByName -> back to B -> A, SH_CALL-> CreateEntityByName -> back to A -> back to O

Is there a way to bypass only current hook to get correct sequence?

O -> B, SH_CALL-> A, SH_CALL-> CreateEntityByName -> back to A -> back to B -> back to O

You should split your hooks into separate pre and post hooks rather than using SH_CALL.

That could be a way, how can I get the result CBaseEntity pointer in the posthook ?

META_RESULT_ORIG_RET

(the dumb anti-shouting feature won't let me post that as all caps without writing more text.)

Thanks, it works.

CBaseEntity* pEntity = META_RESULT_ORIG_RET(CBaseEntity*);

I have to keep a variable to pass some data from pre to post hook, but anyway it's much better than checking and processing double calls inside the original function.
