Importing memory 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. The imported memory object holds a reference to its payload.
Applications can import the same payload into multiple instances of Vulkan, into the same instance from which it was exported, and multiple times into a given Vulkan instance. In all cases, each import operation must create a distinct VkDeviceMemory object.
handleType is not 0, it must be supported for import, as reported by VkExternalImageFormatProperties or VkExternalBufferPropertiesfd was exported must have been created on the same underlying physical device as devicehandleType is not 0, it must be EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_FD_BIT or EXTERNAL_MEMORY_HANDLE_TYPE_DMA_BUF_BIT_EXThandleType is not 0, fd must be a valid handle of the type specified by handleTypefd must have been created from a physical device and driver that is compatible with device and handleType, as described in External memory handle types compatibilityfd must obey any requirements listed for handleType in external memory handle types compatibilitysType must be STRUCTURE_TYPE_IMPORT_MEMORY_FD_INFO_KHRhandleType is not 0, handleType must be a valid VkExternalMemoryHandleTypeFlagBits value
