| <description summary="Internal protocol for buffer sharing using Vulkan external memory"> |
| This protocol is used internally by Qt for implementing the |
| qt_server_buffer extension on hardware that supports Vulkan external memory . |
| |
| This protocol is not part of the Qt API. It exists purely as an |
| implementation detail and may change from version to |
| version without notice, or even be removed. |

| <event name="server_buffer_created"> |
| <description summary="vulkan buffer information"> |
| Informs the client about a newly created server buffer. |
| The "fd" argument is a POSIX file descriptor representing the |
| underlying resources of a Vulkan device memory object as defined |
| in the GL_EXT_memory_object_fd extension. |
