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 can be used to provide additional device queue 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-flags-06225
    flags must be equal to VkDeviceQueueCreateInfo::flags for a VkDeviceQueueCreateInfo structure for the queue family indicated by queueFamilyIndex when device was created

  • VUID-VkDeviceQueueInfo2-queueIndex-01843
    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)

  • 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
