-- | VkImportMemoryHostPointerInfoEXT - import memory from a host pointer
--
-- = Description
--
-- Importing memory from a host pointer shares ownership of the memory
-- between the host and the Vulkan implementation. The application /can/
-- continue to access the memory through the host pointer but it is the
-- application’s responsibility to synchronize device and non-device access
-- to the underlying memory as defined in [Host Access to Device Memory
-- Objects](https://www.khronos.org/registry/vulkan/specs/1.0-extensions/html/vkspec.html#memory-device-hostaccess).
--
-- Applications /can/ import the same underlying memory into multiple
-- instances of Vulkan and multiple times into a given Vulkan instance.
-- However, implementations /may/ fail to import the same underlying memory
-- multiple times into a given physical device due to platform constraints.
--
-- Importing memory from a particular host pointer /may/ not be possible
-- due to additional platform-specific restrictions beyond the scope of
-- this specification in which case the implementation /must/ fail the
-- memory import operation with the error code
-- @VK_ERROR_INVALID_EXTERNAL_HANDLE_KHR@.
--
-- The application /must/ ensure that the imported memory range remains
-- valid and accessible for the lifetime of the imported memory object.
--
-- == Valid Usage
--
-- -   If @handleType@ is not @0@, it /must/ be supported for import, as
--     reported in
--     'Graphics.Vulkan.Extensions.VK_KHR_external_memory_capabilities.VkExternalMemoryPropertiesKHR'
--
-- -   If @handleType@ is not @0@, it /must/ be
--     @VK_EXTERNAL_MEMORY_HANDLE_TYPE_HOST_ALLOCATION_BIT_EXT@ or
--     @VK_EXTERNAL_MEMORY_HANDLE_TYPE_HOST_MAPPED_FOREIGN_MEMORY_BIT_EXT@
--
-- -   @pHostPointer@ /must/ be a pointer aligned to an integer multiple of
--     @VkPhysicalDeviceExternalMemoryHostPropertiesEXT@::@minImportedHostPointerAlignment@
--
-- -   If @handleType@ is
--     @VK_EXTERNAL_MEMORY_HANDLE_TYPE_HOST_ALLOCATION_BIT_EXT@,
--     @pHostPointer@ /must/ be a pointer to @allocationSize@ number of
--     bytes of host memory, where @allocationSize@ is the member of the
--     @VkMemoryAllocateInfo@ structure this structure is chained to
--
-- -   If @handleType@ is
--     @VK_EXTERNAL_MEMORY_HANDLE_TYPE_HOST_MAPPED_FOREIGN_MEMORY_BIT_EXT@,
--     @pHostPointer@ /must/ be a pointer to @allocationSize@ number of
--     bytes of host mapped foreign memory, where @allocationSize@ is the
--     member of the @VkMemoryAllocateInfo@ structure this structure is
--     chained to
--
-- == Valid Usage (Implicit)
