--
-- == Description
--
-- An application using external memory may wish to synchronize access to
-- that memory using fences. This extension enables an application to
-- export fence payload to and import fence payload from POSIX file
-- descriptors.
--
-- == New Commands
--
-- -   'getFenceFdKHR'
--
-- -   'importFenceFdKHR'
--
-- == New Structures
--
-- -   'FenceGetFdInfoKHR'
--
-- -   'ImportFenceFdInfoKHR'
--
-- == New Enum Constants
--
-- -   'KHR_EXTERNAL_FENCE_FD_EXTENSION_NAME'
--
-- -   'KHR_EXTERNAL_FENCE_FD_SPEC_VERSION'
--
-- -   Extending 'Vulkan.Core10.Enums.StructureType.StructureType':
--
--     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_FENCE_GET_FD_INFO_KHR'
--
--     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_IMPORT_FENCE_FD_INFO_KHR'
--
-- == Issues
--
-- This extension borrows concepts, semantics, and language from
-- @VK_KHR_external_semaphore_fd@. That extension’s issues apply equally to
-- this extension.

-- | vkGetFenceFdKHR - Get a POSIX file descriptor handle for a fence
--
-- = Description
--
-- Each call to 'getFenceFdKHR' /must/ create a new file descriptor and
-- transfer ownership of it to the application. To avoid leaking resources,
-- the application /must/ release ownership of the file descriptor when it
-- is no longer needed.
--
-- Note
--
-- Ownership can be released in many ways. For example, the application can
-- call @close@() on the file descriptor, or transfer ownership back to
-- Vulkan by using the file descriptor to import a fence payload.
--
-- If @pGetFdInfo->handleType@ is
-- 'Vulkan.Core11.Enums.ExternalFenceHandleTypeFlagBits.EXTERNAL_FENCE_HANDLE_TYPE_SYNC_FD_BIT'
-- and the fence is signaled at the time 'getFenceFdKHR' is called, @pFd@
-- /may/ return the value @-1@ instead of a valid file descriptor.
--
-- Where supported by the operating system, the implementation /must/ set
-- the file descriptor to be closed automatically when an @execve@ system
-- call is made.
--
-- Exporting a file descriptor from a fence /may/ have side effects
-- depending on the transference of the specified handle type, as described
-- in
-- <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#synchronization-fences-importing Importing Fence State>.

--
-- Applications /can/ import the same fence payload into multiple instances
-- of Vulkan, into the same instance from which it was exported, and
-- multiple times into a given Vulkan instance.

--
-- Handle Types Supported by 'ImportFenceFdInfoKHR'
--
-- == Valid Usage
--
-- -   #VUID-VkImportFenceFdInfoKHR-handleType-01464# @handleType@ /must/
--     be a value included in the
--     <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#synchronization-fence-handletypes-fd Handle Types Supported by >
--     table
--
-- -   #VUID-VkImportFenceFdInfoKHR-fd-01541# @fd@ /must/ obey any
--     requirements listed for @handleType@ in
--     <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#external-fence-handle-types-compatibility external fence handle types compatibility>
--
-- If @handleType@ is
-- 'Vulkan.Core11.Enums.ExternalFenceHandleTypeFlagBits.EXTERNAL_FENCE_HANDLE_TYPE_SYNC_FD_BIT',
-- the special value @-1@ for @fd@ is treated like a valid sync file
-- descriptor referring to an object that has already signaled. The import
-- operation will succeed and the 'Vulkan.Core10.Handles.Fence' will have a
-- temporarily imported payload as if a valid file descriptor had been
-- provided.
--
-- Note
--
-- This special behavior for importing an invalid sync file descriptor
-- allows easier interoperability with other system APIs which use the
-- convention that an invalid sync file descriptor represents work that has
-- already completed and does not need to be waited for. It is consistent
-- with the option for implementations to return a @-1@ file descriptor
-- when exporting a
-- 'Vulkan.Core11.Enums.ExternalFenceHandleTypeFlagBits.EXTERNAL_FENCE_HANDLE_TYPE_SYNC_FD_BIT'
-- from a 'Vulkan.Core10.Handles.Fence' which is signaled.
--
-- == Valid Usage (Implicit)
--
-- -   #VUID-VkImportFenceFdInfoKHR-sType-sType# @sType@ /must/ be
--     'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_IMPORT_FENCE_FD_INFO_KHR'
--
-- -   #VUID-VkImportFenceFdInfoKHR-pNext-pNext# @pNext@ /must/ be @NULL@
--
-- -   #VUID-VkImportFenceFdInfoKHR-fence-parameter# @fence@ /must/ be a
--     valid 'Vulkan.Core10.Handles.Fence' handle
--
-- -   #VUID-VkImportFenceFdInfoKHR-flags-parameter# @flags@ /must/ be a
--     valid combination of
--     'Vulkan.Core11.Enums.FenceImportFlagBits.FenceImportFlagBits' values
--
-- -   #VUID-VkImportFenceFdInfoKHR-handleType-parameter# @handleType@
--     /must/ be a valid
--     'Vulkan.Core11.Enums.ExternalFenceHandleTypeFlagBits.ExternalFenceHandleTypeFlagBits'
--     value
--
-- == Host Synchronization
