#define INCL_GPIPATHS
 
BOOL GpiCloseFigure(hps)
HPS hps;    /* presentation-space handle */
 
The GpiCloseFigure function closes an open figure in a path bracket. A
figure is open unless it is explicitly closed by using the GpiCloseFigure
function. A figure can be open even if the current point and the starting
point of the figure are equal.
 
Parameter  Description
────────────────────────────────────────────────────────────────────────────
 
hps        Identifies the presentation space.
 
Return Value
 
The return value is GPI_OK if the function is successful or GPI_ERROR if an
error occurred.
 
Errors
 
Use the WinGetLastError function to retrieve the error value, which may be
one of the following:
 
     PMERR_INV_HPS
     PMERR_PS_BUSY
 
Example
 
This example uses the GpiCloseFigure function to close a triangle drawn in a
path bracket. The triangle starts at (0,0). Since the current position just
before the GpiCloseFigure is (200,0), the function closes the triangle by
drawing a line from (200,0) to (0,0).
 
HPS hps;
POINTL ptlStart = { 0, 0 };
POINTL ptlPoints[] = { 100, 100, 200, 0 };
 
GpiBeginPath(hps, 1L);                  /* start the path bracket */
GpiMove(hps, &ptlStart);                /* move to starting point */
GpiPolyLine(hps, 2L, ptlPoints);        /* draw the three sides   */
GpiCloseFigure(hps);                    /* close the triangle     */
GpiEndPath(hps);                        /* end the path bracket   */
