  NAME

    fg_priority - Determines frame buffer output priority of the frame grabber

  LIBRARY

    Intergraph Device Library (libix.a)

  SYNOPSIS

    #include <sys/xio/xerr.h>

    int fg_priority(
      int fgno ,
      int fbno );

  PARAMETERS

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

    fbno   The frame buffer number

  DESCRIPTION

    The fg_priority() function determines the source of video output when both
    frame buffers are in FG_DISPLAY mode.  If fbno is zero, frame buffer 0 is
    the source of video output.  Otherwise, frame buffer 1 is the source of
    video output.

    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_priority() 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.
