+=head1 NAME
+
+SSL_set_fd - connect the SSL object with a file descriptor
+
+=head1 SYNOPSIS
+
+ #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);
+
+=head1 DESCRIPTION
+
+SSL_set_fd() sets the file descriptor B<fd> as the input/output facility
+for the TLS/SSL (encrypted) side of B<ssl>. B<fd> will typically be the
+socket file descriptor of a network connection.
+
+When performing the operation, a B<socket BIO> is automatically created to
+interface between the B<ssl> and B<fd>. The BIO and hence the SSL engine
+inherit the behaviour of B<fd>. If B<fd> is non-blocking, the B<ssl> will
+also have non-blocking behaviour.
+
+If there was already a BIO connected to B<ssl>, BIO_free() will be called
+(for both the reading and writing side, if different).
+
+SSL_set_rfd() and SSL_set_wfd() perform the respective action, but only
+for the read channel or the write channel, which can be set independently.
+
+=head1 RETURN VALUES
+
+The following return values can occur:
+
+=over 4
+
+=item 0
+
+The operation failed. Check the error stack to find out why.
+
+=item 1
+
+The operation succeeded.
