\doxysubsection{Detailed Description}
These constants are all instantiations of the \doxylink{class_qore_1_1_file}{File class}

None of these constants are available if the parse option \doxylink{group__parse__options_gaa92bf6eafb76a4ccf1a0d0df45b13363}{PO\+\_\+\+NO\+\_\+\+TERMINAL\+\_\+\+IO} is set
