#include <openssl/ssl.h>
int SSL_get_fd(const SSL *ssl);

SSL_get_rfd() and SSL_get_wfd() return the file descriptors for the

write channel are different, SSL_get_fd() will return the file descriptor
of the read channel.

- -1
-
The operation failed, because the underlying BIO is not of the correct type
(suitable for file descriptors).
- >=0
-
