+} XSegment; +.De +.LP +All x and y members are signed integers. +The width and height members are 16-bit unsigned integers. +You should be careful not to generate coordinates and sizes +out of the 16-bit ranges, because the protocol only has 16-bit fields +for these values. +.SH DIAGNOSTICS +.TP 1i +.ZN BadDrawable +A value for a Drawable argument does not name a defined Window or Pixmap. +.TP 1i +.ZN BadGC +A value for a GContext argument does not name a defined GContext. +.TP 1i +.ZN BadMatch +An +.ZN InputOnly +window is used as a Drawable. +.TP 1i +.ZN 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. +.TP 1i +.ZN 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.
