vkCreateQueryPool

Create a new query pool object

To create a query pool, call:

VkResult vkCreateQueryPool(
    VkDevice device,
    const VkQueryPoolCreateInfo* pCreateInfo,
    const VkAllocationCallbacks* pAllocator,
    VkQueryPool* pQueryPool);
  • device is the logical device that creates the query pool.
  • pCreateInfo is a pointer to a VkQueryPoolCreateInfo structure containing the number and type of queries to be managed by the pool.
  • pAllocator controls host memory allocation as described in the Memory Allocation chapter.
  • pQueryPool is a pointer to a VkQueryPool handle in which the resulting query pool object is returned.
