Re: [sc-dev] SC -> c++ interface

[Charlls Quarra <charlls_quarra@xxxxxxxxxxxx>]

I see in SCUM_Prim.cpp that you define some primitives
as "_SCUM_View_DoSomething". Is this simply a naming
convention or the _ are translated as some member 
operator into the sc language? I see a similar pattern
in the LangPrimSource

 Anyhow, this name you feed into the definePrimitive
call is not the same name that those primitives are
known from the sc language. Where the actual names (sc
names of the primitives) are stored?
