Description

Depending on the specified mode, XChangeSaveSet() either inserts or deletes the specified window from the client's save-set. The specified window must have been created by some other client, or a BadMatch error results.

XChangeSaveSet() can generate BadMatch , BadValue , and BadWindow errors.

Diagnostics

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.
BadWindow A value for a Window argument does not name a defined Window.
