1991-2006 Silicon Graphics, Inc. glXGetContextIDEXT 3G glXGetContextIDEXT get the XID for a context. GLXContextID glXGetContextIDEXT const GLXContext ctx ctx Specifies a GLX rendering context. 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 _glxextstring(EXT_import_context) is included in the string returned by glXQueryExtensionsString, when called with argument GLX_EXTENSIONS, extension EXT_import_context is supported. GLXBadContext is generated if ctx does not refer to a valid context. glXCreateContext, glXQueryVersion, glXQueryExtensionsString Copyright 1991-2006 Silicon Graphics, Inc.
