XSetTextProperty(3X11) XLIB FUNCTIONS XSetTextProperty(3X11)
NAME
XSetTextProperty, XGetTextProperty - set and read text pro-
perties
SYNTAX
void XSetTextProperty(Display *display, Window w, XTextPro-
perty *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 speci-
fied property for the named window with the data, type, for-
mat, 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 for-
mat 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 particu-
lar 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 XTextPro-
perty structure, XGetTextProperty returns a nonzero status;
otherwise, it returns a zero status.
