gsmult



PURPOSE

Draws a multiline, a set of lines that connect alternate pairs of points in a
sequence.

C SYNTAX

int gsmult_ (number, x, y)

int *number, *x, *y;

FORTRAN SYNTAX

INTEGER function gsmult (number, x, y)

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

PASCAL SYNTAX

FUNCTION gsmult_ (

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

DESCRIPTION

The gsmult subroutine draws lines, as defined by the current relevant
attributes, between alternate 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 a multiple of 2, with 2 as the minimum value.

x, y              Define the points for line drawing.

GSMULT(3g,L)                AIX Technical Reference                GSMULT(3g,L)



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.
