\subsection{Detailed Description}
The process class manages an asynchronous process with redirected IO. 

No console window is being created.

To use, spawn the process and, since it\textquotesingle{}s blocking, call read from a different thread. \begin{Desc}

Stops the spawned process. 

This function doesn\textquotesingle{}t actually kill the process, it merely closes the pipes.

Blocks until the process has quit. \mbox{\Hypertarget{classfz_1_1process_a22ad3ef13eba91f03285364cf3610df8}\label{classfz_1_1process_a22ad3ef13eba91f03285364cf3610df8}}

\subsubsection{\texorpdfstring{read()}{read()}}
{\footnotesize\ttfamily int read (\begin{DoxyParamCaption}\item[{char $\ast$}]{buffer,  }\item[{unsigned int}]{len }\end{DoxyParamCaption})}



Read data from process. 

This function blocks

\begin{DoxyReturn}{Returns}
$>$0 Number of octets read, can be less than requested 

0 on E\+OF 

-\/1 on error.

Start the process. 

This function takes care of properly quoting and escaping the the program\textquotesingle{}s path and its arguments. Fails if process has already been spawned.


\begin{DoxyParams}{Parameters}
{\em cmd} & The path of the program to execute \\
\hline
{\em args} & The command-\/line arguments for the process.\\
\hline
\end{DoxyParams}
\begin{DoxyNote}{Note}
May return {\ttfamily true} even if the process cannot be started. In that case, trying to read from the process will fail with an error or E\+OF.

Write data data process. 

This function blocks

true if all octets have been written. 

false on error.
