How to interpret this declaration

[Mark]

Hmm,it is a little difficult.The signal functions is one of POSIX.

Not POSIX, ISO 7.14.1.1

That gives my compiler an error:
error C2091: function returns function

This compiles OK:
typedef int (*signal_f) (int);
signal_f signal (int sig, signal_f * function);

No. The right code is:

typedef int (*signal_f) (int);
signal_f signal (int sig, signal_f function);

or

typedef int signal_f (int);
signal_f *signal (int sig, signal_f *function);
