C Specification

To destroy a query pool, call:

// Provided by VK_VERSION_1_0
void vkDestroyQueryPool(
    VkDevice                                    device,
    VkQueryPool                                 queryPool,
    const VkAllocationCallbacks*                pAllocator);


  • device is the logical device that destroys the query pool.

  • queryPool is the query pool to destroy.

  • pAllocator controls host memory allocation as described in the Memory Allocation chapter.


Valid Usage
  • VUID-vkDestroyQueryPool-queryPool-00793
    All submitted commands that refer to queryPool must have completed execution

  • VUID-vkDestroyQueryPool-queryPool-00794
    If VkAllocationCallbacks were provided when queryPool was created, a compatible set of callbacks must be provided here

  • VUID-vkDestroyQueryPool-queryPool-00795
    If no VkAllocationCallbacks were provided when queryPool was created, pAllocator must be NULL


Applications can verify that queryPool can be destroyed by checking that vkGetQueryPoolResults() without the VK_QUERY_RESULT_PARTIAL_BIT flag returns VK_SUCCESS for all queries that are used in command buffers submitted for execution.

Valid Usage (Implicit)
  • VUID-vkDestroyQueryPool-device-parameter
    device must be a valid VkDevice handle

  • VUID-vkDestroyQueryPool-queryPool-parameter
    If queryPool is not VK_NULL_HANDLE, queryPool must be a valid VkQueryPool handle

  • VUID-vkDestroyQueryPool-pAllocator-parameter
    If pAllocator is not NULL, pAllocator must be a valid pointer to a valid VkAllocationCallbacks structure

  • VUID-vkDestroyQueryPool-queryPool-parent
    If queryPool is a valid handle, it must have been created, allocated, or retrieved from device

Host Synchronization
  • Host access to queryPool must be externally synchronized
