getmonitor(3G)

NAME
     getmonitor - returns the video output format currently being generated by
     the graphics system

C SPECIFICATION
     long getmonitor()

PARAMETERS
     none

FUNCTION RETURN VALUE
     The returned value of this function is the type of the current display
     monitor.

DESCRIPTION
     getmonitor returns the type of the current video output format. The
     possible return values are:

     HZ30      30Hz interlaced monitor

     HZ30_SG   30HZ noninterlaced with sync on green monitor

     HZ50      50Hz noninterlaced monitor

     HZ60      60Hz noninterlaced monitor

     HZ70      70Hz noninterlaced monitor

     HZ72      72Hz noninterlaced monitor

     HZ76      76Hz noninterlaced monitor

     IRIS3K    60Hz (1024x768 visible) noninterlaced video format, if the
               video hardware supports it

     NTSC      NTSC monitor

     PAL       PAL or SECAM monitor

     STR_RECT  monitor in stereo mode

     SGI_VIDEO_FORMAT_OTHER
               an video output format other than those explicitly defined
               above

NOTES
     This routine has been superseded by the functions that are part of the X
     extension XSGIvc(3) for those hardware architectures that natively
     support OpenGL.
     This routine is available only in immediate mode.

     The symbolic return values mentioned above are defined in <gl/get.h>.

     This function returns the value set previously by setmonitor.  It does
     not actually test the hardware.  Because Iris Entry does not support
     setmonitor the value returned by getmonitor is always HZ60.  Iris Elan
     and Extreme support HZ50, HZ60, HZ72, NTSC, PAL and STR_RECT monitor
     types.
