--
-- == Description
--
-- An application may wish to reference device memory in multiple Vulkan
-- logical devices or instances, in multiple processes, and\/or in multiple
-- APIs. This extension enables an application to export POSIX file
-- descriptor handles from Vulkan memory objects and to import Vulkan
-- memory objects from POSIX file descriptor handles exported from other
-- Vulkan memory objects or from similar resources in other APIs.
--
-- == New Commands
--
-- -   'getMemoryFdKHR'
--
-- -   'getMemoryFdPropertiesKHR'
--
-- == New Structures
--
-- -   'MemoryFdPropertiesKHR'
--
-- -   'MemoryGetFdInfoKHR'
--
-- -   Extending 'Vulkan.Core10.Memory.MemoryAllocateInfo':
--
--     -   'ImportMemoryFdInfoKHR'
--
-- == New Enum Constants
--
-- -   'KHR_EXTERNAL_MEMORY_FD_EXTENSION_NAME'
--
-- -   'KHR_EXTERNAL_MEMORY_FD_SPEC_VERSION'
--
-- -   Extending 'Vulkan.Core10.Enums.StructureType.StructureType':
--
--     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_IMPORT_MEMORY_FD_INFO_KHR'
--
--     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_MEMORY_FD_PROPERTIES_KHR'
--
--     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_MEMORY_GET_FD_INFO_KHR'
--
-- == Issues
--
-- 1) Does the application need to close the file descriptor returned by
-- 'getMemoryFdKHR'?
--
-- __RESOLVED__: Yes, unless it is passed back in to a driver instance to
-- import the memory. A successful get call transfers ownership of the file
-- descriptor to the application, and a successful import transfers it back
-- to the driver. Destroying the original memory object will not close the
-- file descriptor or remove its reference to the underlying memory
-- resource associated with it.
--
-- 2) Do drivers ever need to expose multiple file descriptors per memory
-- object?
--
-- __RESOLVED__: No. This would indicate there are actually multiple memory
-- objects, rather than a single memory object.
--
-- 3) How should the valid size and memory type for POSIX file descriptor
-- memory handles created outside of Vulkan be specified?
--
-- __RESOLVED__: The valid memory types are queried directly from the
-- external handle. The size will be specified by future extensions that
-- introduce such external memory handle types.
