XSetWMName(3)				  XLIB FUNCTIONS			    XSetWMName(3)

NAME
       XSetWMName, XGetWMName, XStoreName, XFetchName - set or read a window's WM_NAME property

SYNTAX
       void XSetWMName(Display *display, Window w, XTextProperty *text_prop);

       Status XGetWMName(Display *display, Window w, XTextProperty *text_prop_return);

       int XStoreName(Display *display, Window w, char *window_name);

       Status XFetchName(Display *display, Window w, char **window_name_return);

ARGUMENTS
       display	 Specifies the connection to the X server.

       text_prop Specifies the XTextProperty structure to be used.

       text_prop_return
		 Returns the XTextProperty structure.

       w	 Specifies the window.

       window_name
		 Specifies the window name, which should be a null-terminated string.

       window_name_return
		 Returns the window name, which is a null-terminated string.

DESCRIPTION
       The XSetWMName convenience function calls XSetTextProperty to set the WM_NAME property.

       The XGetWMName convenience function calls XGetTextProperty to obtain the WM_NAME property.
       It returns a nonzero status on success; otherwise, it returns a zero status.

       The XStoreName function assigns the name passed to window_name to the specified window.	A
       window manager can display the window name in some prominent place, such as the title bar,
       to allow users to identify windows easily.  Some window managers may display a window's
       name in the window's icon, although they are encouraged to use the window's icon name if
       one is provided by the application.  If the string is not in the Host Portable Character
       Encoding, the result is implementation-dependent.

       XStoreName can generate BadAlloc and BadWindow errors.

       The XFetchName function returns the name of the specified window.  If it succeeds, it
       returns a nonzero status; otherwise, no name has been set for the window, and it returns
       zero.  If the WM_NAME property has not been set for this window, XFetchName sets win-
       dow_name_return to NULL.  If the data returned by the server is in the Latin Portable
       Character Encoding, then the returned string is in the Host Portable Character Encoding.
       Otherwise, the result is implementation-dependent.  When finished with it, a client must
       free the window name string using XFree.

       XFetchName can generate a BadWindow error.

PROPERTIES
       WM_NAME	 The name of the application.

DIAGNOSTICS
       BadAlloc  The server failed to allocate the requested resource or server memory.

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