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);

pub fn create_query_pool(
    device: vk::Device,
    p_create_info: *const vk::QueryPoolCreateInfo,
    p_allocator: *const vk::AllocationCallbacks,
    p_query_pool: *mut vk::QueryPool,
) -> vk::Result;

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.
