Static method that creates a new IOSharedDataQueue instance with the specified number of entries of the given size.
Number of entries to allocate space for.
Size of each entry.
Reeturns the newly allocated IOSharedDataQueue instance. Zero is returned on failure.
This method will create a new IOSharedDataQueue instance with enough capacity for numEntries of entrySize. It does account for the IODataQueueEntry overhead for each entry. Note that the numEntries and entrySize are simply used to determine the data region size. They do not actually restrict the size of number of entries that can be added to the queue.
This method allocates a new IODataQueue instance and then calls initWithEntries() with the given numEntries and entrySize parameters. If the initWithEntries() fails, the new instance is released and zero is returned.
