DESCRIPTION
       glXQueryContextInfoEXT  returns the the visual id,  screen  number,  and
       share list of _param2. This call may cause a round trip to the server.

       glXQueryContextInfoEXT  is part of the EXT_import_context extension, not
       part of the core GLX command set. If GLX_EXT_import_context is  included
       in the string returned by glXQueryExtensionsString, when called with ar‐
       gument GLX_EXTENSIONS, extension EXT_import_context is supported.

ERRORS
       GLXBadContext is generated if _param2 does not refer to a valid context.
