.SH ARGUMENTS
.IP \fIdisplay\fP 1i
Specifies the connection to the X server.
.IP \fIscreen_number\fP 1i
Specifies the appropriate screen number on the host server.
.IP \fIvalue_mask\fP 1i
Specifies which values are to be set using information in
the values structure.
This mask is the bitwise inclusive OR of the valid configure window values bits.
.IP \fIvalues\fP 1i
Specifies the 
.ZN XWindowChanges 
structure.
.IP \fIw\fP 1i
Specifies the window.
.SH DESCRIPTION
The 
.ZN XIconifyWindow 
function sends a WM_CHANGE_STATE 
.ZN ClientMessage 
event with a format of 32 and a first data element of 
.ZN IconicState 
(as described in section 4.1.4 of the 
\fIInter-Client Communication Conventions Manual\fP)
and a window of w
to the root window of the specified screen
with an event mask set to
.ZN SubstructureNotifyMask |
.ZN SubstructureRedirectMask .
Window managers may elect to receive this message and
if the window is in its normal state, 
may treat it as a request to change the window's state from normal to iconic.
If the WM_CHANGE_STATE property cannot be interned, 
.ZN XIconifyWindow
does not send a message and returns a zero status.
It returns a nonzero status if the client message is sent successfully;
otherwise, it returns a zero status.
.LP
The 
.ZN XWithdrawWindow 
function unmaps the specified window 
and sends a synthetic 
.ZN UnmapNotify 
event to the root window of the specified screen.
Window managers may elect to receive this message 
and may treat it as a request to change the window's state to withdrawn.
When a window is in the withdrawn state, 
neither its normal nor its iconic representations is visible.
It returns a nonzero status if the 
.ZN UnmapNotify 
event is successfully sent; 
otherwise, it returns a zero status.
.LP
.ZN XWithdrawWindow
can generate a
.ZN BadWindow
error.
.LP
The 
.ZN XReconfigureWMWindow 
function issues a 
.ZN ConfigureWindow 
request on the specified top-level window.
If the stacking mode is changed and the request fails with a 
.ZN BadMatch 
error, 
the error is trapped by Xlib and a synthetic 
.ZN ConfigureRequestEvent 
containing the same configuration parameters is sent to the root 
of the specified window.
Window managers may elect to receive this event 
and treat it as a request to reconfigure the indicated window.
It returns a nonzero status if the request or event is successfully sent;
otherwise, it returns a zero status.
.LP
.ZN XReconfigureWMWindow
can generate
.ZN BadValue
and
.ZN BadWindow
errors.
.SH DIAGNOSTICS
.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.  Any argument defined as a set of
alternatives can generate this error.
.TP 1i
.ZN BadWindow
A value for a Window argument does not name a defined Window.
