EnqueueWithCoalesce

Adds an entry to the queue, but doesn’t automatically send a data-available notification.

Declaration

kern_return_t EnqueueWithCoalesce(uint32_t dataSize, bool *sendDataAvailable, IODataQueueClientEnqueueEntryBlock callback);

Parameters

  • dataSize:

    The size of the data to enqueue.

  • sendDataAvailable:

    A Boolean value that indicates that this method would have sent a notification. Initialize the value to false, and then make one or more calls to this method. If the value is true after all of those calls, call the Senddataavailable method yourself to deliver the notification.

  • callback:

    The callback to execute when there is enough space to enqueue the data.

Return Value

kIOReturnSuccess on success, kIOReturnOverrun if the queue was full, or kIOReturnError if the queue is corrupt. See Error Codes.
