<function>glXFreeContextEXT</function> frees the client-side part of a GLXContext that
was created with <citerefentry><refentrytitle>glXImportContextEXT</refentrytitle></citerefentry>. <function>glXFreeContextEXT</function> does not
free the server-side context information or the XID
associated with the server-side context.
</para>
<para>
<function>glXFreeContextEXT</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_vertex_array</code> is supported.

<constant>GLXBadContext</constant> is generated if <parameter>ctx</parameter> does not
