DESCRIPTION
sgiXnmbxQueryExtension returns True if the SGI-
NewMultibuffering extension is available on the given
display. If the extension exists, the value of the first
event code (which should be added to the event type constant
sgiXNMBX_ClobberNotify and sgiXNMBX_UpdateNotify to get the
actual values) is stored into event_base_return and the
value of the first error code (which should be added to the
error type constant sgiNMBX_BadBuffer and
sgiNMBX_BadCapability to the actual values) is store into
error_base_return.
sgiXnmbxGetVersion gets the major and minor version numbers
of the extension. The return value is zero if an error
occurs or non-zero if no error happens.
