/* RETURNS() and RETURN() are macros that can be used if a class object is
being returned. They make use of the GNU C-Compiler's named return value
feature, if available. In this case, the class object isn't returned and
copied, but the result itself is filled.
RETURNS(ReturnType, FunctionDeclaration, Result)
... function-body working on Result ...
RETURN(Result)
A function like this (cXYZ is a class type):
cXYZ myfunction(int a, char *b) {
cXYZ result;
... something happens with result ...
return result;
}
can be written like this:
RETURNS(cXYZ, myfunction(int a, char *b), result)
... something happens with result ...
RETURN(result)
