The obvious (void *) does not work, except by accident on some machines
(and, depending on the machine, some segmentation models).  (void *) only
works for pointers to data.

For your example below,

typedef int (*TYPE)(char *);
>int foo(buff) char *buff; { return atoi(buff); }
>TYPE bar() { return foo; }

Alternatively,

int (*bar())(char *) { return foo; }

I recommend the typedef.
