FUNCTION: preg\_\-match 
\begin{DoxyParams}{Parameters}
\item[{\em expr}]Regular expression to be matched \item[{\em str}]String to be checked \item[{\em matches}]Reference to a char$\ast$$\ast$ that will contain the submatches (NULL if you don't need it) \item[{\em nmatches}]Reference to a int containing the number of submatches found (NULL if you don't need it) \end{DoxyParams}
\begin{DoxyReturn}{Returns}
-\/1 if the regex is wrong, 0 if no match was found, 1 otherwise 
\end{DoxyReturn}
