TITLE: Address of inline functions and methods


PROBLEM: x9999bvj@maple.circa.ufl.edu, 13 Dec 92

What is the official method for handling taking the address of an inline
function?


RESPONSE: dgrammel@dgrammel.mentorg.com

Don't make it inline.

Nonsense.  An inline function is just a function.  You take its address
in exactly the same way as you would any function of its type.
Examples:

	inline int ordinary(int i) { return i; }

	int (*fp)(int) = ordinary;

	class X {
	public:
	    int member(int i) { return i; } // inline
	};

	int (X::*mfp)(int) = &X::member;

In such cases, the compiler will create a callable version of the
inline function for you, and use that address.  You could then have
both inline and non-inline uses of the function in the same program.
Continuing the previous examples:

	foo()
	{
	    int j = ordinary(3);	// expanded inline
	    int k = fp(4);		// called via the pointer
	    ...
	}
