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

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