C SPECIFICATION

       GLXContextID glXGetContextIDEXT( const GLXContext )

PARAMETERS

       GLXContext  Specifies a GLX rendering context.

DESCRIPTION

       glXGetContextIDEXT returns the XID associated with a GLXContext.

       No  round trip is forced to the server; unlike most X calls that return
       a value, glXGetContextIDEXT does not flush any pending events.

       glXGetContextIDEXT 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
       argument GLX_EXTENSIONS, extension EXT_import_context is supported.

ERRORS

       GLXBadContext is generated if GLXContext does not refer to a valid con-
       text.
