XSetTextProperty(3X11) XLIB FUNCTIONS XSetTextProperty(3X11)
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 XTextProp-
erty 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.

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 argu-
ment, 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.
