--
-- == Description
--
-- An application using external memory may wish to synchronize access to
-- that memory using semaphores. This extension enables an application to
-- export semaphore payload to and import semaphore payload from POSIX file
-- descriptors.
--
-- == New Commands
--
-- -   'getSemaphoreFdKHR'
--
-- -   'importSemaphoreFdKHR'
--
-- == New Structures
--
-- -   'ImportSemaphoreFdInfoKHR'
--
-- -   'SemaphoreGetFdInfoKHR'
--
-- == New Enum Constants
--
-- -   'KHR_EXTERNAL_SEMAPHORE_FD_EXTENSION_NAME'
--
-- -   'KHR_EXTERNAL_SEMAPHORE_FD_SPEC_VERSION'
--
-- -   Extending 'Vulkan.Core10.Enums.StructureType.StructureType':
--
--     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_IMPORT_SEMAPHORE_FD_INFO_KHR'
--
--     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_SEMAPHORE_GET_FD_INFO_KHR'
--
-- == Issues
--
-- 1) Does the application need to close the file descriptor returned by
-- 'getSemaphoreFdKHR'?
--
-- __RESOLVED__: Yes, unless it is passed back in to a driver instance to
-- import the semaphore. 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 semaphore object will not
-- close the file descriptor or remove its reference to the underlying
-- semaphore resource associated with it.
