VKDESTROYQUERYPOOL(3)

NAME
vkDestroyQueryPool - Destroy a query pool object

C SPECIFICATION

    void vkDestroyQueryPool(
        VkDevice                                    device,
        VkQueryPool                                 queryPool,
        const VkAllocationCallbacks*                pAllocator);

PARAMETERS

device
    Logical device which owns the object.

queryPool
    The handle of the object to destroy.

DESCRIPTION

vkDestroyQueryPool destroys the query pool whose handle is specified in queryPool, which must be a valid handle to a query pool that was created by device. Attempts to destroy VK_NULL_HANDLE are silently ignored. After a query pool has been destroyed, its handle becomes invalid and should not be accessed again.

VALID USAGE

    • device must be a valid VkDevice handle

    • If queryPool is not VK_NULL_HANDLE, queryPool must be a valid VkQueryPool handle

    • If pAllocator is not NULL, pAllocator must be a pointer to a valid VkAllocationCallbacks structure

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

    • Each of device and queryPool that are valid handles must have been created, allocated or retrieved from the same VkPhysicalDevice

    • All submitted commands that refer to queryPool must have completed execution

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

    • If no VkAllocationCallbacks were provided when queryPool was created, pAllocator must be NULL

HOST SYNCHRONIZATION

    • Host access to queryPool must be externally synchronized
