The mt allocator [hereinafter referred to simply as "the allocator"]
|
|
|
|
|
|
is a fixed size (power of two) allocator that was initially
|
|
|
|
|
|
developed specifically to suit the needs of multi threaded
|
|
|
|
|
|
applications [hereinafter referred to as an MT application]. Over
|
|
|
|
|
|
time the allocator has evolved and been improved in many ways, in
|
|
|
|
|
|
particular it now also does a good job in single threaded
|
|
|
|
|
|
applications [hereinafter referred to as a ST application]. (Note:
|
|
|
|
|
|
In this document, when referring to single threaded applications
|
|
|
|
|
|
this also includes applications that are compiled with gcc without
|
|
|
|
|
|
thread support enabled. This is accomplished using ifdef's on
|
|
|
|
|
|
__GTHREADS). This allocator is tunable, very flexible, and capable
|
|
|
|
|
|
of high-performance.
|
|
|
|
|
|
</p><p>
|
|
|
|
|
|
The aim of this document is to describe - from an application point of
|
|
|
|
|
|
view - the "inner workings" of the allocator.
