XDrawPoints

Syntax

XDrawPoints(display, d, gc, points, npoints, mode)
      Display *display;
      Drawable d;
      GC gc;
      XPoint *points;
      int npoints;
      int mode;

Arguments

display	Specifies the connection to the X server.
d	Specifies the drawable.
gc	Specifies the GC.
points	Specifies an array of points.
npoints	Specifies the number of points in the array.
mode	Specifies the coordinate mode. You can pass CoordModeOrigin or CoordModePrevious.

Description

XDrawPoints() draws multiple points the same way XDrawPoint() draws one point. CoordModeOrigin treats all coordinates as relative to the origin, and CoordModePrevious treats all coordinates after the first as relative to the previous point. XDrawPoints() draws the points in the order listed in the array.

This function uses these GC components: function, plane-mask, foreground, subwindow-mode, clip-x-origin, clip-y-origin, and clip-mask. XDrawPoints() can generate BadDrawable , BadGC , BadMatch , and BadValue errors.

Diagnostics

BadDrawable	A value for a Drawable argument does not name a defined Window or Pixmap.
BadGC	A value for a GContext argument does not name a defined GContext.
BadMatch	An InputOnly window is used as a Drawable.
BadMatch	Some argument or pair of arguments has the correct type and range but fails to match in some other way required by the request.
BadValue	Some numeric value falls outside the range of values accepted by the request. Unless a specific range is specified for an argument, the full range defined by the argument's type is accepted. Any argument defined as a set of alternatives can generate this error.
