C Specification

The VkDeviceQueueInfo2 structure is defined as:

// Provided by VK_VERSION_1_1
typedef struct VkDeviceQueueInfo2 {
    VkStructureType             sType;
    const void*                 pNext;
    VkDeviceQueueCreateFlags    flags;
    uint32_t                    queueFamilyIndex;
    uint32_t                    queueIndex;
} VkDeviceQueueInfo2;

Members

  • sType is the type of this structure.

  • pNext is NULL or a pointer to a structure extending this structure. The pNext chain of VkDeviceQueueInfo2 is used to provide additional image parameters to vkGetDeviceQueue2.

  • flags is a VkDeviceQueueCreateFlags value indicating the flags used to create the device queue.

  • queueFamilyIndex is the index of the queue family to which the queue belongs.

  • queueIndex is the index within this queue family of the queue to retrieve.

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 instance. If no matching flags were specified at device creation time, then the handle returned in pQueue must be NULL.

Valid Usage

  • VUID-VkDeviceQueueInfo2-queueFamilyIndex-01842
    queueFamilyIndex must be one of the queue family indices specified when device was created, via the VkDeviceQueueCreateInfo structure

  • VUID-VkDeviceQueueInfo2-queueIndex-01843
    queueIndex must be less than the number of queues created for the specified queue family index and VkDeviceQueueCreateFlags member flags equal to this flags value when device was created, via the queueCount member of the VkDeviceQueueCreateInfo structure

Valid Usage (Implicit)

  • VUID-VkDeviceQueueInfo2-sType-sType
    sType must be VK_STRUCTURE_TYPE_DEVICE_QUEUE_INFO_2

  • VUID-VkDeviceQueueInfo2-pNext-pNext
    pNext must be NULL

  • VUID-VkDeviceQueueInfo2-flags-parameter
    flags must be a valid combination of VkDeviceQueueCreateFlagBits values
