CHECK_NULL()

multiple_free()

void multiple_free	(	void *	p,
			... )

Function to free memory using the free() function.

Calls free on a variable number of arguments. The last argument must be NULL.

Example of use:

int *p1, *p2, *p3;
 
MALLOC(p1, 10); // Allocates an array of 10 ints.
MALLOC(p2, 10);
MALLOC(p3, 10);
// ...
multiple_free(p1, p2, p3, NULL);

Attention

This function is dangerous and should only be used if you know what you are doing! The pointers to be freed must not be NULL. In the example above, if p2 is NULL, p3 will not be freed, which can cause a memory leak.
