## Public Member Functions
| pmt_pool (size_t itemsize, size_t alignment=16, size_t allocation_size=4096, size_t max_items=0)
| ~pmt_pool ()

void | free (void *p)

## 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::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.

## ◆ ~pmt_pool()

## Member Function Documentation

## ◆ free()

void pmt::pmt_pool::free | ( | void * | p | ) |

## ◆ malloc()
