DESCRIPTION
The 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 structure. If the property does not already exist, sets it for the specified window.

can generate and errors.

The function reads the specified property from the window and stores the data in the returned 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, sets the value field to NULL, the encoding field to the format field to zero, and the nitems field to zero.

If it was able to read and store the data in the structure, returns a nonzero status; otherwise, it returns a zero status.
