conn |
The XCB connection to X11. |
response_type
The type of this reply, in this case XCB_SHM_QUERY_VERSION. This field is also present in the xcb_generic_reply_t and can be used to tell replies apart from each other.
sequence |
The sequence number of the last request processed by the X11 server. | ||
length |
The length of the reply, in words (a word is 4 bytes). |
shared_pixmaps
True if the server supports shared pixmaps, otherwise false.
major_version
The major version of the extension supported.
minor_version
The minor version of the extension supported.
uid |
The UID of the server. |
|||
gid |
The GID of the server. |
pixmap_format
TODO: NOT YET DOCUMENTED.
This is used to determine the version of the MIT-SHM extension supported by the X server. Clients MUST NOT make other requests in this extension until a reply to this requests indicates the X server supports them.
Returns an xcb_shm_query_version_cookie_t. Errors have to be handled when calling the reply function xcb_shm_query_version_reply.
If you want to handle errors in the event loop instead, use xcb_shm_query_version_unchecked. See xcb-requests(3) for details.
This request does never generate any errors.
