From MSDN

#include <stdio.h>

typedef int (*myintchartype) (char *, char *);
typedef void (*myvoidtype) (void);
typedef int (*myintvoidtype) (void);

int func1(char *, char *);
void func2(void);

void main(void)
{
myintvoidtype ptr;

ptr = (myintvoidtype) func1;
((myintchartype) ptr)("one", "two");

ptr = (myintvoidtype) func2;
((myvoidtype) ptr)();
}

int func1(char *a, char *b)
{
return printf("func1 took two parameters: %s and %s\n", a, b);
}

void func2(void)
{
printf("func2 did not take any parameters\n");
}
