Initializes the variation using the following rules\-:
\begin{DoxyItemize}
\item Boolean options are initialized to S\-D\-L\-\_\-\-F\-A\-L\-S\-E.
\item Integer options are initialized to the minimum valid value they can hold.
\item Enum options are initialized to the first element in the list of values they can take.
\item String options are initialized to the name of the option.
\end{DoxyItemize}

\begin{DoxyReturn}{Returns}
1 on success, 0 on failure.

Converts a variation object into a string of command line arguments.


\begin{DoxyParams}{Parameters}
{\em variation} & Variation object to be converted. \\
\hline
{\em config} & Config object for the S\-U\-T. \\
\hline
{\em buffer} & Pointer to the buffer the arguments string will be copied into. \\
\hline
{\em size} & Size of the buffer.\\

\char`\"{}\-Increments\char`\"{} the value of the option by one and returns the carry. We wrap around to the initial value on overflow which makes the carry one. For example\-: \char`\"{}incrementing\char`\"{} an S\-D\-L\-\_\-\-F\-A\-L\-S\-E option makes it S\-D\-L\-\_\-\-T\-R\-U\-E with no carry, and \char`\"{}incrementing\char`\"{} an S\-D\-L\-\_\-\-T\-R\-U\-E option makes it S\-D\-L\-\_\-\-F\-A\-L\-S\-E with carry one. For integers, a random value in the valid range for the option is used.


\begin{DoxyParams}{Parameters}
{\em var} & Value of the option \\
\hline
{\em opt} & Object with metadata about the option\\
\hline
\end{DoxyParams}
\begin{DoxyReturn}{Returns}
1 if there is a carry for enum and bool type options, 0 otherwise. 1 is always returned for integer and string type options. -\/1 is returned on error.
