functions returning pointers to functions

[Brad Needham]

I think your confusion comes from the two ways of declaring a function:
	1) with other declarations
	2) with the function definition (i.e. the code for the function).
Formal parameters do not appear when you declare a function separately
from its definition, e.g.
	int *a();
vs
	int *a(x)
	int x;
	{
		...
	}
If you want a function returning a pointer to a function returning an int,
you can say it two ways:
	1) as a declaration:
		int (*getroutine())();
	2) or as a declaration and definition:
		int (*getroutine(name,table))()
		char *name;
		struct atable *table;
		{
			...
		}

Because the declaration of functions is so confusing, Graham Ross of Tektronix,
MDP wrote a program to convert between English and C declarations.  He posted
it to net.sources quite a while ago, but I'm sure he can get a copy to you.
He is tektronix!tekmdp!grahamr.
