| 42 | <function>glXGetContextIDEXT</function> returns the XID associated with a GLXContext. |

| 44 | <para> |
| 45 | No round trip is forced to the server; unlike most X calls that |
| 46 | return a value, <function>glXGetContextIDEXT</function> does not flush any pending events. |
| 47 | </para> |
| 48 | <para> |
| 49 | <function>glXGetContextIDEXT</function> is part of the <code>EXT_import_context</code> extension, |
| 50 | not part of the core GLX command set. If _glxextstring(EXT_import_context) |
| 51 | is included in the string returned by <citerefentry><refentrytitle>glXQueryExtensionsString</refentrytitle></citerefentry>, |
| 52 | when called with argument <constant>GLX_EXTENSIONS</constant>, |
| 53 | extension <code>EXT_import_context</code> is supported. |
