|
|
\subsubsection*{Arguments}
|
|
Objects passed to \code{mkdir}:
|
|
\begin{itemize}
|
|
\item{\code{fs}: pointer to the FileSystem object}
|
|
\item{\code{dir}: pointer to the path + name of the new directory}
|
|
\end{itemize}
|
|
\subsubsection*{Return value}

|
|
\item{Returns -3 if no free space is available to create the directory.}
|
|
\end{itemize}
|
|

\lstset{numbers=left, stepnumber=1, numberstyle=\small, numbersep=5pt, tabsize=4}
