Window w;
XTextProperty *text_prop_return;
Atom property;
Arguments
display Specifies a connection to an X server; returned from
XOpenDisplay().
w Specifies the window.
text_prop_return

property Specifies the property name.

DescriptionXGetTextProperty() 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 number) 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 set these files in the XTextProperty structure, XGet‐
TextProperty() returns a non-zero status; otherwise, it returns a zero
status.
