Function Documentation

void heap_free	(	struct Heap *	h,
		void *	mem
	)

Free a block of memory, determining its size automatically.

Parameters:

	h	Heap from which the block was allocated.
	mem	Pointer to a block of memory previously allocated with either heap_malloc() or heap_calloc().

Note:

If mem is a NULL pointer, no operation is performed.

Freeing the same memory block twice has undefined behavior.

This function works like the ANSI C free().
