what is void?

Is it a string? noooo...
Is it an integer? noooo...
Is it a char? noooo...

It is superman!

Ehm.. Superman is not proper C code it is fiction so it should not be in your code

Whoa, what is this supposed to be doing and what are you doing with it?

Almost any pointer will convert to a void *, however a void * will not convert to another pointer type unless you use a typecast. Declaring a pointer to a function is shown below.

void *x;               // pointer to whatever
void (*fPtr)(int);   // pointer to a function of the form void f(int)

void foo(int)
{
	x = foo;		// No worries here
	fPtr = foo;	// As intended
	fPtr = x;		// Error!
}
