I don't know what to say, this is how you're supposed to call these 
"objc_msgSend" functions. They part of the Objective-C runtime.

In C, if I call it like it's declare, returning void, I get a segfault:

NSRect foo (id screen)
{
     NSRect rect;
     ((void (*)(NSRect*, id, SEL))objc_msgSend_stret)(&rect, screen, 
sel_registerName("visibleFrame"));
     return rect;
}

Don't ask me why it works like this.
