So I have a series of global functions, say:
foo_f1(int a, int b, char *c);
foo_f2(int a);
foo_f3(char *a);
I want to make a C++ wrapper around these, something like:
MyFoo::f1(int a, int b, char* c);
MyFoo::f2(int a);
MyFoo::f3(char* a);
There's about 40 functions like this, 35 of them I just want to pass through to the global function, the other 5 I want to do something different with.
Ideally the implementation of MyFoo.cpp would be something like:
PASSTHRU( f1, (int a, int b, char *c) );
PASSTHRU( f2, (int a) );
MyFoo::f3(char *a)
{
//do my own thing here
}
But I'm having trouble figuring out an elegant way to make the above PASSTHRU macro.
What I really need is something like the mythical X getArgs() below:
MyFoo::f1(int a, int b, char *c)
{
X args = getArgs();
args++; //skip past implicit this..
::f1(args); //pass args to global function
}
But short of dropping into assembly I can't find a good implementation of getArgs().
