Syntax

VOID v_ellarc( handle, x, y, xradius, yradius, startangle, endangle)
WORD handle, x, y, xradius, yradius, startangle, endangle;

Function      v_ellarc() outputs an elliptical arc segment.

Sub-Opcode    6

Availability  Supported by all drivers. This function composes one of the
              10 VDI GDP's (Generalized Drawing Primitives). Although all
              current drivers support all GDP's, their availability is
              not guaranteed and may vary. To check for a particular GDP
              refer to the table returned by v_opnvwk() or v_opnwk().

Parameters    handle specifies a valid workstation handle. x and y specify
              the coordinates of the center of an arc with an X radius of
              xradius and a Y radius of yradius. Only the portion of the
              arc which falls between the angles specified in startangle
              and endangle will be drawn. Angles are specified in tenths
              of degrees as follows:



Binding       contrl[0] = 11;
              contrl[1] = contrl[3] = 2;
              contrl[5] = 6;
              contrl[6] = handle;

              intin[0] = startangle;
              intin[1] = endangle;

              ptsin[0] = x;
              ptsin[1] = y;
              ptsin[2] = xradius;
              ptsin[3] = yradius;
