- .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.
- .SH "SEE ALSO"
- .IX Header "SEE ALSO"
- \&\fBssl\fR\|(7)
