H A DIODataQueue.h88 * @discussion This method will create a new IODataQueue 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.<br> This method allocates a new IODataQueue instance and then calls initWithEntries() with the given numEntries and entrySize parameters.
