# VkAcquireProfilingLockInfoKHR(3) Manual Page

## Name

VkAcquireProfilingLockInfoKHR - Structure specifying parameters to acquire the profiling lock

## C Specification

The `VkAcquireProfilingLockInfoKHR` structure is defined as:

    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 an extension-specific 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)

- `sType` must be `VK_STRUCTURE_TYPE_ACQUIRE_PROFILING_LOCK_INFO_KHR`

- `pNext` must be `NULL`

- `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.
