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
       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.
