Member Function Documentation

virtual void MemoryDividerX::MDXMarkingHandler::mdxPerformMarking ( MDXPool pool,
void *  markingParam 
) [pure virtual]

The marking callback itself.

Use MDXPool::mark(void *chunk) and MDXPool::mark(uinta count, void **chunks) to actually mark the wanted blocks. Use MDXPool::isMarked(void *chunk), MDXPool::getFlags(void *chunk) or MDXPool::getFlags(uinta count, MDXFlags *flags) to determine whether or not a block's already been marked.

The marking callback must not allocate or free memory. Also it must not change the settings of any block's flags, except for FLAG_MARKED, which is set when a block is marked.

Parameters:
poolThe address of the MDXPool object managing the memory to be marked.
markingParamThe value of MDXConfiguration::markingParam from the pool's MDXConfiguration structure.
