a7d27d5a
JR
203\fISSL_set_fd()\fR sets the file descriptor \fBfd\fR as the input/output facility
204for the TLS/SSL (encrypted) side of \fBssl\fR. \fBfd\fR will typically be the
984263bc
MD
205socket file descriptor of a network connection.
206.PP
a7d27d5a
JR
207When performing the operation, a \fBsocket BIO\fR is automatically created to
208interface between the \fBssl\fR and \fBfd\fR. The BIO and hence the SSL engine
984263bc
MD
209inherit the behaviour of \fBfd\fR. If \fBfd\fR is non-blocking, the \fBssl\fR will
210also have non-blocking behaviour.
211.PP
a7d27d5a 212If there was already a BIO connected to \fBssl\fR, \fIBIO_free()\fR will be called
984263bc
MD
213(for both the reading and writing side, if different).
214.PP
a7d27d5a 215\fISSL_set_rfd()\fR and \fISSL_set_wfd()\fR perform the respective action, but only
984263bc
MD
216for the read channel or the write channel, which can be set independently.
217.SH "RETURN VALUES"
984263bc
MD
218The following return values can occur:
219.Ip "0" 4
220The operation failed. Check the error stack to find out why.
221.Ip "1" 4
984263bc
MD
222The operation succeeded.
