C Specification

The VkAcquireProfilingLockInfoKHR structure is defined as:

// Provided by VK_KHR_performance_query
typedef struct VkAcquireProfilingLockInfoKHR {
    VkStructureType                   sType;
    const void*                       pNext;
    VkAcquireProfilingLockFlagsKHR    flags;
    uint64_t                          timeout;
} VkAcquireProfilingLockInfoKHR;

Members

  • sType is the type of this structure.

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

  • flags is reserved for future use.

  • timeout indicates how long the function waits, in nanoseconds, if the profiling lock is not available.

Description

Valid Usage (Implicit)
  • VUID-VkAcquireProfilingLockInfoKHR-sType-sType
    sType must be VK_STRUCTURE_TYPE_ACQUIRE_PROFILING_LOCK_INFO_KHR

  • VUID-VkAcquireProfilingLockInfoKHR-pNext-pNext
    pNext must be NULL

  • VUID-VkAcquireProfilingLockInfoKHR-flags-zerobitmask
    flags must be 0

If timeout is 0, vkAcquireProfilingLockKHR will not block while attempting to acquire the profling lock. If timeout is UINT64_MAX, the function will not return until the profiling lock was acquired.
