XDrawPoint(3X) XDrawPoint(3X)
NAME
XDrawPoint, XDrawPoints - draw points
SYNOPSIS
XDrawPoint(display, d, gc, x, y)
Display *display;
Drawable d;
GC gc;
int x, y;
XDrawPoints(display, d, gc, points, npoints, mode)
Display *display;
Drawable d;
GC gc;
XPoint *points;
int npoints;
int mode;
ARGUMENTS
d Specifies the drawable.
display Specifies the connection to the X server.
gc Specifies the GC.
mode Specifies the coordinate mode. You can pass
CoordModeOrigin or CoordModePrevious.
npoints Specifies the number of points in the array.
points Specifies a pointer to an array of points.
x
y Specify the x and y coordinates where you
want the point drawn.
DESCRIPTION
The XDrawPoint function uses the foreground pixel and
function components of the GC to draw a single point
into the specified drawable; XDrawPoints draws multiple
points this way. 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.
Both functions use these GC components: function,
plane-mask, foreground, subwindow-mode, clip-x-origin,
clip-y-origin, and clip-mask.
XDrawPoint can generate BadDrawable, BadGC, and
BadMatch errors. XDrawPoint 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.
