DESCRIPTION
The XSetTextProperty function replaces the existing speci-
fied 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, XSet-
TextProperty 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 contain-
ing 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, XGet-
TextProperty 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.
