Description

XGetTextProperty() 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, XGetTextProperty() returns a non-zero status; otherwise, it returns a zero status. For more information, see Volume One, Chapter 10, Interclient Communication.
