To import a fence payload from a POSIX file descriptor, call:
VkResult vkImportFenceFdKHR( VkDevice device, const VkImportFenceFdInfoKHR* pImportFenceFdInfo);
deviceis the logical device that created the fence.
pImportFenceFdInfois a pointer to a VkImportFenceFdInfoKHR structure specifying the fence and import parameters.
Importing a fence payload from a file descriptor transfers ownership of the file descriptor from the application to the Vulkan implementation. The application must not perform any operations on the file descriptor after a successful import.
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.
