.SH DESCRIPTION
|
||
|
|
\f3glXQueryVersion\fP returns the major and minor version numbers of the GLX extension
|
||
|
|
implemented by the server associated with connection \f2dpy\fP.
|
||
|
|
Implementations with the same major version number are upward compatible,
|
||
|
|
meaning that the implementation with the higher minor number is a superset
|
||
|
|
of the version with the lower minor number.
|
||
|
|
.P
|
||
|
|
\f2major\fP and \f2minor\fP do not return values if they are specified as
|
||
|
|
\f3NULL\fP.
|
||
|
|
.SH ERRORS
|
||
|
|
\f3glXQueryVersion\fP returns \f3False\fP if it fails,
|
||
|
|
\f3True\fP otherwise.
|
||
|
|
.P
|
||
|
|
\f2major\fP and \f2minor\fP are not updated when \f3False\fP is returned.
