gspoly(3) — AIX/RT 2.2.1

gspoly

Purpose

     Draws a polyline, a set of lines that connects a sequence
     of points.

C Syntax

     int gspoly_ (number, x, y)

     int *number, *x, *y;

FORTRAN Syntax

     INTEGER function gspoly (number, x, y)

     INTEGER number, x (*), y (*)

Pascal Syntax

     FUNCTION gspoly_ (

     VAR number: INTEGER;
     VAR x, y: ARRAY [1..k| of INTEGER
     ): INTEGER [PUBLIC|;

Description

     The  gspoly subroutine  draws  lines, as  defined by  the
     current relevant attributes, between  each pair of points
     defined by the parameters.

     The relevant attributes are:

     o   Color map
     o   Plane mask
     o   Line color index
     o   Line style
     o   Logical operation.

     Parameters

     number            Defines  the number  of  points in  the
                       coordinate arrays.  It must be Y 2.

     x, y              Define the points for line drawing.

     For  Pascal,  the  application must  declare  the  arrays
     passed as being  fixed length and declare  the routine as
     accepting arrays  of that length.   The k in  the routine
     declaration must be a constant.

Return Value

     GS_SUCC   Successful.
     GS_CORD   Invalid coordinate.
     GS_NCOR   Invalid number of coordinates.
     GS_INAC   Virtual terminal inactive.
