#define ALLOC	(		s,
			t,
			n,
			v
	)

High-tide structure allocator for use in linked lists.

Using a free-list with the name of NAME_freelist, return a single element. The type of the element must be a structure with a field named next. When the free-list is empty, memory is claimed from the system in blocks. Elements may be returned to the pool by linking them into the free-list.

Parameters

s	The number of structures in the block.
t	The structure type.
n	The NAME portion of the NAME_freelist free-list.
v	The destination of the pointer to the allocated element. The contents of the allocated element will be memset to 0.

#define FREE	(		n,
			p
	)

Value:

do {                        \
        p->next = n##_freelist; \
		n##_freelist = p;     \
    } while (0)

Free a block allocated by ALLOC.

Parameters

n	The NAME portion of the NAME_freelist free-list.
p	The pointer to the block to be freed.
