  NAME

    fg_blank - Blanks the output signal of the frame grabber

  LIBRARY

    Intergraph Device Library (libix.a)

  SYNOPSIS

    #include <sys/xio/xerr.h>

    int fg_blank(
      int fgno ,
      int mode );

  PARAMETERS

    fgno   The location of the frame grabber on the Shared Resource (SR) Bus

    mode   An integer mode flag

  DESCRIPTION

    The fg_blank() function forces the output video to be blanked when mode is
    nonzero.  If mode is zero, the output video is sourced from one of the
    frame buffers.

    The fgno parameter specifies the location of the frame grabber on the
    Shared Resource (SR) Bus.  The frame grabber in the lowest SR Bus slot
    will be addressed by 0.

  RETURN VALUES

    Upon successful completion, a value of 0 is returned.  Otherwise, one of
    the following failure codes is returned.

  ERRORS

    The fg_blank() function will fail if one of the following is true:

    [XIO_FAILURE]
           The system does not contain the driver needed to support this
           request.

    [FG_NOT_OWNER]
           The specified frame grabber was not allocated by the calling
           process.
