|

_`.over.buffer.class`: The pool uses the simplest buffer class,
|
||||
BufferClass. This is appropriate since these buffers don't attach to
|
||||
segments, and hence don't constrain buffered regions to lie within
|
||||
``BufferClass``. This is appropriate since these buffers don't attach
|

to segments, and hence don't constrain buffered regions to lie within

Methods
|
||||
-------
|
||||
|
||||
_`.method`: The MVFF pool supports the following methods:
|
||||
|
||||
``Res MVFFInit(Pool pool, Args arg)``
|
||||
|
||||
_`.method.init`: This takes six `keyword arguments`_:
|
||||
|
||||
.. _`keyword arguments`: keyword-arguments
|
||||
|
||||
================================== ============================================
|
||||
Keyword argument Description
|
||||
================================== ============================================
|
||||
``MPS_KEY_EXTEND_BY`` The segment size.
|
||||
``MPS_KEY_MEAN_SIZE`` The average object size.
|
||||
``MPS_KEY_ALIGN`` The alignment of allocations and frees.
|
||||
Must be at least ``sizeof(void *)``.
|
||||
``MPS_KEY_MVFF_SLOT_HIGH`` Whether to allocate objects at the end of
|
||||
free blocks found, as opposed to at
|
||||
the start (for unbuffered
|
||||
allocation).
|
||||
``MPS_KEY_MVFF_ARENA_HIGH`` Whether to express ``SegPrefHIGH``
|
||||
to the arena, as opposed to
|
||||
``SegPrefLOW``.
|
||||
``MPS_KEY_MVFF_FIRST_FIT`` whether to use the suitable block of lowest
|
||||
address, as opposed to the highest
|
||||
(for unbuffered allocation)
|
||||
================================== ============================================
|
||||
|
||||
_`.method.init.epdl`: To simulate the EPDL pool, specify ``extendBy``,
|
||||
``avgSize``, and ``maxSize`` as normal, and use ``slotHigh=FALSE``,
|
||||
``arenaHigh=FALSE``, ``firstFit=TRUE``.
|
||||
|
||||
_`.method.init.epdr`: To simulate the EPDR pool, specify ``extendBy``,
|
||||
``avgSize``, and ``maxSize`` as normal, and use ``slotHigh=TRUE``,
|
||||
``arenaHigh=TRUE``, ``firstFit=TRUE``.
|
||||
|
||||
_`.method.init.other`: The performance characteristics of other
|
||||
combinations are unknown.
|
||||
|
||||
_`.method.alloc`: ``PoolAlloc()`` and ``PoolFree()`` methods are
|
||||
supported, implementing the policy set by the pool params (see
|
||||
`.method.init`_).
|
||||
|
||||
_`.method.buffer`: The buffer methods implement a worst-fit fill
|
||||
strategy.
|
||||
|
||||
|
||||
External Functions
|
||||
------------------
|
||||
|
||||
_`.function`: MVFF supports the following external functions:
|
||||
|
||||
_`.function.free-size`: ``mps_mvff_free_size()`` returns the total
|
||||
size of free space in segments allocated to the MVFF pool instance.
|
||||
|
||||
_`.function.size`: ``mps_mvff_size()`` returns the total memory used
|
||||
by pool segments, whether free or allocated.
|
||||
|
||||
_`.function.class`: ``mps_class_mvff()`` returns the class object for
|
||||
the pool class, to be used in pool creation.

||||

||||

||||
