+
+SSL_get_fd, SSL_get_rfd, SSL_get_wfd - get file descriptor linked to an SSL object
+
+=head1 SYNOPSIS
+
+ #include <openssl/ssl.h>
+
+ int SSL_get_fd(const SSL *ssl);
+ int SSL_get_rfd(const SSL *ssl);
+ int SSL_get_wfd(const SSL *ssl);
+
+=head1 DESCRIPTION
+
+SSL_get_fd() returns the file descriptor which is linked to B<ssl>.
+SSL_get_rfd() and SSL_get_wfd() return the file descriptors for the
+read or the write channel, which can be different. If the read and the
+write channel are different, SSL_get_fd() will return the file descriptor
+of the read channel.
+
+=head1 RETURN VALUES
+
+The following return values can occur:
+
+=over 4
+
+=item -1
+
+The operation failed, because the underlying BIO is not of the correct type
+(suitable for file descriptors).
+
+=item E<gt>=0
+
+The file descriptor linked to B<ssl>.
