XSetTextProperty(3)              XLIB FUNCTIONS             XSetTextProperty(3)

NAME
       XSetTextProperty, XGetTextProperty - set and read text properties

SYNTAX

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

       Status  XGetTextProperty(Display  *display,  Window   w,   XTextProperty
              *text_prop_return, Atom property);

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 struc-
       ture.  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 win-
       dow  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  prop-
       erty'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 struc-
       ture, 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 ac-
                 cepted.   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.
