public class VkDeviceQueueInfo2
extends org.lwjgl.system.Struct
implements org.lwjgl.system.NativeResource
```
Structure specifying the parameters used for device queue creation.
Description

The queue returned by vkGetDeviceQueue2 must have the same flags value from this structure as that used at device creation time in a VkDeviceQueueCreateInfo structure. If no matching flags were specified at device creation time, then the handle returned in pQueue must be NULL.

Valid Usage
- queueFamilyIndex must be one of the queue family indices specified when device was created, via the VkDeviceQueueCreateInfo structure
- flags must be equal to VkDeviceQueueCreateInfo::flags for a VkDeviceQueueCreateInfo structure for the queue family indicated by queueFamilyIndex when device was created
- queueIndex must be less than VkDeviceQueueCreateInfo::queueCount for the corresponding queue family and flags indicated by queueFamilyIndex and flags when device was created
Valid Usage (Implicit)
- sType must be STRUCTURE_TYPE_DEVICE_QUEUE_INFO_2
- pNext must be NULL
- flags must be a valid combination of VkDeviceQueueCreateFlagBits values
