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.
