No round trip is forced to the server; unlike most X calls that

return a value, <function>glXGetContextIDEXT</function> does not flush any pending events.

<para>
|

|
|
<function>glXGetContextIDEXT</function> is part of the <code>EXT_import_context</code> extension,
|
||
|
|
not part of the core GLX command set. If _glxextstring(EXT_import_context)
|
||
|
|
is included in the string returned by <citerefentry><refentrytitle>glXQueryExtensionsString</refentrytitle></citerefentry>,
|
||
|

when called with argument <constant>GLX_EXTENSIONS</constant>,
|
||
|
|
extension <code>EXT_import_context</code> is supported.
