Try this:

	extern int (*getmenu())();

Explanation:

	int   X   ();		- X is a function returning int.
	int (*X  )();		- X is a pointer to a function returning int.
	int (*X())();		- X is a function returning a pointer
				  to a function returning int.

Alternative preferred by me:

	typedef int (*FUNC)();	/* FUNC - pointer to a function returning int */

	FUNC func;
	extern FUNC getmenu();
