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 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 nonzero; 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 window_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
