.SH DESCRIPTION
|
|
\f3glXQueryExtension\fP returns \f3True\fP if the X server of
|
|
connection \f2dpy\fP supports the GLX extension,
|
|
\f3False\fP otherwise.
|
|
If \f3True\fP is returned,
|
|
then \f2errorBase\fP and \f2eventBase\fP return the error base and event base of
|
|
the GLX extension.
|
|
Otherwise, \f2errorBase\fP and \f2eventBase\fP are unchanged.
|
|
.P
|
|
\f2errorBase\fP and \f2eventBase\fP do not return values if they are specified
|
|
as \f3NULL\fP.
|
|
.SH NOTES
|
|
\f2eventBase\fP is included for future extensions.
|
|
GLX does not currently define any events.
