#include <stdio.h> struct X { int x; void (*fp)(struct X *); }; void func1(struct X *xobj) { printf("%s, %d\n", __FUNCTION__, xobj->x); } void func2(struct X *xobj) { printf("%s, %d\n", __FUNCTION__, xobj->x); } main() { struct X obj; obj.x = 10; obj.fp = func1; obj.fp(&obj); obj.x = 20; obj.fp = func2; obj.fp(&obj); }
Output
$ ./a.out func1, 10 func2, 20
Cool eh?
