Macro Definition Documentation

#define as_queue_inita	(		__q,
			__item_size,
			__capacity
	)

Value:

(__q)->data = alloca((__capacity) * (__item_size));\
(__q)->capacity = __capacity;\
(__q)->head = (__q)->tail = 0;\
(__q)->item_size = __item_size;\
(__q)->total = 0;\
(__q)->flags = 0;

Initialize a stack allocated as_queue, with item storage on the stack. as_queue_inita() will transfer stack memory to the heap if a resize is required.
