vkGetMemoryFdPropertiesKHR

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:

VkResult vkGetMemoryFdPropertiesKHR(
    VkDevice device,
    VkExternalMemoryHandleTypeFlagBits handleType,
    int fd,
    VkMemoryFdPropertiesKHR* pMemoryFdProperties);

• device is the logical device that will be importing fd.
• handleType is a VkExternalMemoryHandleTypeFlagBits value specifying the type of the handle fd.
• fd is the handle which will be imported.
• pMemoryFdProperties is a pointer to a VkMemoryFdPropertiesKHR structure in which the properties of the handle fd are returned.
