Set a marking callback by setting MDXConfiguration::markingHandler to point to an instance of MDXMarkingHandler.

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. MDXPool::mark(void *chunk) also returns wether or not the block was already marked before it was called. 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

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