Quote:(* Replaces original function with the new one with the same prototype and 1-2 extra arguments.
Calling convention is changed to STDCALL. The new argument is callable pointer, which can be used to
execute original function. The pointer is passed as THE FIRST argument. If custom parameter address
is given, the value of custom parameter will be passed to handler as THE SECOND argument. If AppliedPatch
pointer is given, it will be assigned an opaque pointer to applied patch data structure. This
pointer can be used to rollback the patch (remove splicing).
Returns address of the bridge to original function *)
