Problem for passing a selector function as argument

I have experience in Objective C but not in C/C++

I have a function
void GamePlay::myArgumentFunction () {
printf(“myArgumentFunction”);
}

when I call this function
void GamePlay::functionToGetSelector(SEL_CallFunc *sel);

I need to pass myArgumentFunction() as argument to functionToGetSelector() function…

how can I do that?

thank in advance.

functionToGetSelector(callfunc_selector(GamePlay::myArgumentFunction))
