gdk:gl-context-debug-enabled (context)

context -- a gdk:gl-context object
enabled -- a boolean whether debugging is enabled

The gdk:gl-context-debug-enabled function retrieves whether debugging is enabled. The (setf gdk:gl-context-debug-enabled) function sets whether the GL context should perform extra validations and run time checking. This is useful during development, but has additional overhead.

The gdk:gl-context object must not be realized or made current prior to calling this function.
