Detailed Description

very simple thread-safe fixed-size allocation pool

FIXME may want to go to global allocation with per-thread free list. This would eliminate virtually all lock contention.

Constructor & Destructor Documentation

pmt_pool::pmt_pool	(	size_t	itemsize,
		size_t	alignment = 16,
		size_t	allocation_size = 4096,
		size_t	max_items = 0
	)

Parameters:

	itemsize	size in bytes of the items to be allocated.
	alignment	alignment in bytes of all objects to be allocated (must be power-of-2).
	allocation_size	number of bytes to allocate at a time from the underlying allocator.
	max_items	is the maximum number of items to allocate. If this number is exceeded, the allocate blocks. 0 implies no limit.
