.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fISSL_get_fd()\fR returns the file descriptor which is linked to \fBssl\fR.
\&\fISSL_get_rfd()\fR and \fISSL_get_wfd()\fR return the file descriptors for the
read or the write channel, which can be different. If the read and the
write channel are different, \fISSL_get_fd()\fR will return the file descriptor
of the read channel.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
The following return values can occur:
.IP "\-1" 4
.IX Item "-1"
The operation failed, because the underlying \s-1BIO\s0 is not of the correct type
(suitable for file descriptors).
.IP ">=0" 4
.IX Item ">=0"
The file descriptor linked to \fBssl\fR.
