.SH PARAMETERS

\f2ctx\fP
Specifies a GLX rendering context.

.SH DESCRIPTION
\f3glXGetContextIDEXT\fP returns the XID associated with a GLXContext.
.P
No round trip is forced to the server; unlike most X calls that
return a value, \f3glXGetContextIDEXT\fP does not flush any pending events.
.P
\f3glXGetContextIDEXT\fP is part of the \f3EXT_import_context\fP extension,
not part of the core GLX command set. If \f3GLX_EXT_import_context\fP
is included in the string returned by \f3glXQueryExtensionsString\fP,
when called with argument \f3GLX_EXTENSIONS\fP,
extension \f3EXT_import_context\fP is supported.

.SH ERRORS
\f3GLXBadContext\fP is generated if \f2ctx\fP does not
refer to a valid context.
