145\&\fISSL_set_fd()\fR sets the file descriptor \fBfd\fR as the input/output facility
146for the \s-1TLS/SSL\s0 (encrypted) side of \fBssl\fR. \fBfd\fR will typically be the
984263bc
MD
147socket file descriptor of a network connection.
148.PP
e056f0e0
JR
149When performing the operation, a \fBsocket \s-1BIO\s0\fR is automatically created to
150interface between the \fBssl\fR and \fBfd\fR. The \s-1BIO\s0 and hence the \s-1SSL\s0 engine
e257b235 151inherit the behaviour of \fBfd\fR. If \fBfd\fR is non-blocking, the \fBssl\fR will
984263bc
MD
152also have non-blocking behaviour.
153.PP
e056f0e0 154If there was already a \s-1BIO\s0 connected to \fBssl\fR, \fIBIO_free()\fR will be called
