|

The cLuaState::Call() family of functions provides a template-based system for calling any Lua function
|
||||
either by name or by reference with almost any number of parameters and return values. This is done by
|
||||
providing a number of overloads of the same name with variable number of template-type parameters. To
|
||||
separate the arguments from the return values, a special type of cLuaState::cRet is used.
