- sType – the type of this structure.
- pNext – NULL or a pointer to an extension-specific structure.
- flags – a bitmask indicating behavior of the queue.
- queueFamilyIndex – an unsigned integer indicating the index of the queue family to create on this device. This index corresponds to the index of an element of the pQueueFamilyProperties array that was returned by vkGetPhysicalDeviceQueueFamilyProperties.
- queueCount – an unsigned integer specifying the number of queues to create in the queue family indicated by queueFamilyIndex.
- pQueuePriorities – an array of queueCount normalized floating point values, specifying priorities of work that will be submitted to each created queue. See Queue Priority for more information.
