+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+The SSL_*\fB_ctrl()\fR family of functions is used to manipulate settings of
+the SSL_CTX and SSL objects. Depending on the command \fBcmd\fR the arguments
+\&\fBlarg\fR, \fBparg\fR, or \fBfp\fR are evaluated. These functions should never
+be called directly. All functionalities needed are made available via
+other functions or macros.
+.SH "RETURN VALUES"
+.IX Header "RETURN VALUES"
+The return values of the SSL*\fB_ctrl()\fR functions depend on the command
+supplied via the \fBcmd\fR parameter.
