C Specification

// Provided by VK_EXT_global_priority_query
typedef struct VkQueueFamilyGlobalPriorityPropertiesEXT {
    VkStructureType             sType;
    void*                       pNext;
    uint32_t                    priorityCount;
    VkQueueGlobalPriorityEXT    priorities[VK_MAX_GLOBAL_PRIORITY_SIZE_EXT];
} VkQueueFamilyGlobalPriorityPropertiesEXT;


  • sType is the type of this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • priorityCount is the number of supported global queue priorities in this queue family, and it must be greater than 0.

  • priorities is an array of VK_MAX_GLOBAL_PRIORITY_SIZE_EXT VkQueueGlobalPriorityEXT enums representing all supported global queue priorities in this queue family. The first priorityCount elements of the array will be valid.


The valid elements of priorities must not contain any duplicate values.

The valid elements of priorities must be a continuous sequence of VkQueueGlobalPriorityEXT enums in the ascending order.


For example, returning priorityCount as 3 with supported priorities as VK_QUEUE_GLOBAL_PRIORITY_LOW_EXT, VK_QUEUE_GLOBAL_PRIORITY_MEDIUM_EXT and VK_QUEUE_GLOBAL_PRIORITY_REALTIME_EXT is not allowed.

Valid Usage (Implicit)
  • VUID-VkQueueFamilyGlobalPriorityPropertiesEXT-sType-sType

  • VUID-VkQueueFamilyGlobalPriorityPropertiesEXT-priorities-parameter
    Any given element of priorities must be a valid VkQueueGlobalPriorityEXT value
