C Specification

The VkPerformanceCounterKHR structure is defined as:

// Provided by VK_KHR_performance_query
typedef struct VkPerformanceCounterKHR {
    VkStructureType                   sType;
    void*                             pNext;
    VkPerformanceCounterUnitKHR       unit;
    VkPerformanceCounterScopeKHR      scope;
    VkPerformanceCounterStorageKHR    storage;
    uint8_t                           uuid[VK_UUID_SIZE];
} VkPerformanceCounterKHR;

Members

  • sType is a VkStructureType value identifying this structure.

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

  • unit is a VkPerformanceCounterUnitKHR specifying the unit that the counter data will record.

  • scope is a VkPerformanceCounterScopeKHR specifying the scope that the counter belongs to.

  • storage is a VkPerformanceCounterStorageKHR specifying the storage type that the counter’s data uses.

  • uuid is an array of size VK_UUID_SIZE, containing 8-bit values that represent a universally unique identifier for the counter of the physical device.
