  NAME

    fg_video_in, fg_video_out - Select the video signal types for I/O

  LIBRARY

    Intergraph Device Library (libix.a)

  SYNOPSIS

    #include <sys/xio/xerr.h>

    int fg_video_in(
      int fgno ,
      int mode );

    int fg_video_out(
      int fgno ,
      int mode );

  PARAMETERS

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

    mode   An integer specifying the type of input to digitize

  DESCRIPTION

    The fg_video_in() function selects the video signal type for the frame
    grabber to digitize.  If mode is zero, the Red Green Blue (RGB) video
    input is digitized.  If mode is nonzero, the National Television Systems
    Committee (NTSC) video input is digitized.

    The fg_video_out() function selects the video signal type generated by the
    frame grabber.  If mode is zero, an RGB video signal is generated.  If
    mode is nonzero, an NTSC video signal is generated.

    The fgno parameter specifies the frame grabber location 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_video_in() and fg_video_out() functions will fail if one of the
    following is true:
