TInterpreter::Execute and non-existing function


in the following sample code I try to call a non-existing function via TInterpreter::Execute. I expect to obtain a non-zero error code, however… I tried the same directly with Cint API and I got, again, error = 0. Might you know where the mistake is?

root [0] TGraph *g = new TGraph()
root [1] int error = 0
root [2] gInterpreter->Execute(g, g->IsA(), "ThisMethodDoesNotExist", "", error)
root [3] error

Many thanks, Kašpi.


To know if a method exist use TClass::GetMethod or TClass::GetMethodWIthPrototype (or TClass::GetMethodAny).
