<P>
The SSL_*_ctrl() family of functions is used to manipulate settings of the
SSL_CTX and SSL objects. Depending on the command <STRONG>cmd</STRONG> the arguments
<STRONG>larg</STRONG>, <STRONG>parg</STRONG>, or <STRONG>fp</STRONG> are evaluated. These functions should never be called directly. All
functionalities needed are made available via other functions or macros.

<P>
<HR>
<H1><A NAME="RETURN_VALUES">RETURN VALUES</A></H1>
<P>
The return values of the SSL*_ctrl() functions depend on the command
supplied via the <STRONG>cmd</STRONG> parameter.
