The XDrawPoint function uses the foreground pixel and function components of the graphics context to draw a single point into the specified drawable, while XDrawPoints draws multiple points into the specified drawable. These functions are not affected by the tile or stipple in the graphics context.
.PN XDrawPoint can generate BadDrawable, BadGC, and BadMatch errors. .PN 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.
