POSIX file descriptor memory handles compatible with Vulkan may also be created by non-Vulkan APIs using methods beyond the scope of this specification. To determine the correct parameters to use when importing such handles, call:
// Provided by VK_KHR_external_memory_fd VkResult vkGetMemoryFdPropertiesKHR( VkDevice device, VkExternalMemoryHandleTypeFlagBits handleType, int fd, VkMemoryFdPropertiesKHR* pMemoryFdProperties);
deviceis the logical device that will be importing
handleTypeis the type of the handle
fdis the handle which will be imported.
pMemoryFdPropertiesis a pointer to a VkMemoryFdPropertiesKHR structure in which the properties of the handle
