Thread: How do I send pointers into this function?

I have the following function declaration:

Code:

extern int function(int *grade, double *average);

How do I send numbers into this function?


I tried:

Code:

int *grade;
double *average;
function(*grade, *average);

I also tried it without the *. Both give me errors..

???

the & means the address

EDIT: Just show lasersights post. You probably want to do what I posted. It is not wrong what you are doing, but I guess the function expects to pass a pointer that actually points at an allocated space.
Try what I posted and try this also:

Code:

int *grade = malloc(sizeof(int));
int *average = malloc(sizeof(int));
function(grade, average);

PERFECT.. thanks
