.SH DESCRIPTION
|
|
The
|
|
.ZN 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
|
|
.ZN XTextProperty
|
|
structure.
|
|
If the property does not already exist,
|
|
.ZN XSetTextProperty
|
|
sets it for the specified window.
|
|
.LP
|
|
.ZN XSetTextProperty
|
|
can generate
|
|
.ZN BadAlloc ,
|
|
.ZN BadAtom ,
|
|
.ZN BadValue ,
|
|
and
|
|
.ZN BadWindow
|
|
errors.
|
|
.LP
|
|
The
|
|
.ZN XGetTextProperty
|
|
function reads the specified property from the window
|
|
and stores the data in the returned
|
|
.ZN 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,
|
|
.ZN XGetTextProperty
|
|
sets the value field to NULL,
|
|
the encoding field to None,
|
|
the format field to zero,
|
|
and the nitems field to zero.
|
|
.LP
|
|
If it was able to read and store the data in the
|
|
.ZN XTextProperty
|
|
structure,
|
|
.ZN XGetTextProperty
|
|
returns a nonzero status;
|
|
otherwise, it returns a zero status.
|
|
.LP
|
|
.ZN XGetTextProperty
|
|
can generate
|
|
.ZN BadAtom
|
|
and
|
|
.ZN BadWindow
|
|
errors.
|
