+.SH NAME
+SSL_set_fd, SSL_set_rfd, SSL_set_wfd \- connect the SSL object with a file descriptor
+.SH SYNOPSIS
+.IX Header "SYNOPSIS"
+.Vb 1
+\& #include <openssl/ssl.h>
+\&
+\& int SSL_set_fd(SSL *ssl, int fd);
+\& int SSL_set_rfd(SSL *ssl, int fd);
+\& int SSL_set_wfd(SSL *ssl, int fd);

+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+\&\fBSSL_set_fd()\fR sets the file descriptor \fBfd\fR as the input/output facility
+for the TLS/SSL (encrypted) side of \fBssl\fR. \fBfd\fR will typically be the
+socket file descriptor of a network connection.
+.PP
+When performing the operation, a \fBsocket BIO\fR is automatically created to
+interface between the \fBssl\fR and \fBfd\fR. The BIO and hence the SSL engine
+inherit the behaviour of \fBfd\fR. If \fBfd\fR is nonblocking, the \fBssl\fR will
+also have nonblocking behaviour.
+.PP
+When used on a QUIC connection SSL object, a \fBdatagram BIO\fR is automatically
+created instead of a \fBsocket BIO\fR. These functions fail if called
+on a QUIC stream SSL object.
+.PP
+If there was already a BIO connected to \fBssl\fR, \fBBIO_free()\fR will be called
+(for both the reading and writing side, if different).
+.PP
+\&\fBSSL_set_rfd()\fR and \fBSSL_set_wfd()\fR perform the respective action, but only
+for the read channel or the write channel, which can be set independently.
+.SH "RETURN VALUES"
+.IX Header "RETURN VALUES"
+The following return values can occur:
+.IP 0 4
+The operation failed. Check the error stack to find out why.
+.IP 1 4
+.IX Item "1"
+The operation succeeded.
+.SH NOTES
+.IX Header "NOTES"
+On Windows, a socket handle is a 64\-bit data type (UINT_PTR), which leads to a
+compiler warning (conversion from 'SOCKET' to 'int', possible loss of data) when
+passing the socket handle to SSL_set_*\fBfd()\fR. For the time being, this warning can
+safely be ignored, because although the Microsoft documentation claims that the
+upper limit is INVALID_SOCKET\-1 (2^64 \- 2), in practice the current \fBsocket()\fR
+implementation returns an index into the kernel handle table, the size of which
+is limited to 2^24.
