          properties

     SYNTAX
          void XSetTextProperty(display, w, text_prop, property)
                Display *display;
                Window w;
                XTextProperty *text_prop;
                Atom property;

          Status XGetTextProperty(display, w, text_prop_return,

     ARGUMENTS
          display   Specifies the connection to the X server.

          property  Specifies the property name.

          text_prop Specifies the XTextProperty structure to be used.

          text_prop_return
                    Returns the XTextProperty structure.

     DESCRIPTION
          The XSetTextProperty function replaces the existing
          specified property for the named window with the data, type,
          format, and number of items determined by the value field,
          the encoding field, the format field, and the nitems field,
          respectively, of the specified XTextProperty structure.  If
          the property does not already exist, XSetTextProperty sets
          it for the specified window.

          XSetTextProperty can generate BadAlloc, BadAtom, BadValue,
          and BadWindow errors.

          The XGetTextProperty function reads the specified property
          from the window and stores the data in the returned
          XTextProperty structure.  It stores the data in the value
          field, the type of the data in the encoding field, the
          format of the data in the format field, and the number of
          items of data in the nitems field.  An extra byte containing
          null (which is not included in the nitems member) is stored
          at the end of the value field of text_prop_return.  The
          particular interpretation of the property's encoding and
          data as text is left to the calling application.  If the
          specified property does not exist on the window,
          XGetTextProperty sets the value field to NULL, the encoding
          field to None, the format field to zero, and the nitems
          field to zero.

          If it was able to read and store the data in the
          XTextProperty structure, XGetTextProperty returns a nonzero
          status; otherwise, it returns a zero status.

          XGetTextProperty can generate BadAtom and BadWindow errors.

     PROPERTIES
          WM_CLIENT_MACHINE
                    The string name of the machine on which the client
                    application is running.

          WM_COMMAND
                    The command and arguments, null-separated, used to
                    invoke the application.

          WM_ICON_NAME
                    The name to be used in an icon.

          WM_NAME   The name of the application.

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

          BadAtom   A value for an Atom argument does not name a
                    defined Atom.

          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.
