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::pmt_pool::pmt_pool ( size_t  itemsize,
size_t  alignment = 16,
size_t  allocation_size = 4096,
size_t  max_items = 0 
)
Parameters:
itemsizesize in bytes of the items to be allocated.
alignmentalignment in bytes of all objects to be allocated (must be power-of-2).
allocation_sizenumber of bytes to allocate at a time from the underlying allocator.
max_itemsis the maximum number of items to allocate. If this number is exceeded, the allocate blocks. 0 implies no limit.
