#146779 - C : pointers of function und pointers of pointers |
Hi
To first I want to say Hello to everyone here. I tought since a few day about pointers of function. I know that in C is pointers important fur speed. I have seen that I can write simply a function and use it next time. I agree that for variable are pointers important but why therefor use pointers to function? I tought the same of pointers of pointers. why and when must we use pointers of pointers ? here ist an exemple : struct node { int data; struct node *link; } typedef struct node *pNode; pNode insert ( node **p, int **value) { ... ... ... } I understand the pointer`s mecanism, but these to points I mentioned are not clar in mine head. Best regards! Cyrille |
