|
GstMemChunk is an atomic chunk allocator. It uses atomic operations
|
|
to allocate fixed size memory regions and is therefore thread safe
|
|
without the overhead of mutexes or other heavyweight locking mechanisms.

The GstMemChunk is used to allocate critical resources for #GstBuffer and

#GstEvent.
