Posted: Tue Mar 13, 2007 1:57 am Post subject: Function Pointers

Function pointers are variables that refer to a function and can CALL that function .

Code:

int set_number(int a, int *b);

//The type matches function return type, and the types in back
//match argument list.
int (*funcpointer)(int, int *);

//Assign function to pointer.
funcpointer = set_number;

//call the function
int a = (*funcpointer)(5, &someint);

Script i learnt ages ago .

TIPS: Classes help .

Code:

void (Class::*Draw)(float);

That code creates a pointer to the class you used .

( Outdated tutorial ? Add updates here and i will post it into my original post )
