SSL_GET_FD(3) OpenSSL SSL_GET_FD(3)
SSL_get_fd - get file descriptor linked to an SSL object
#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);
SSL_get_fd() returns the file descriptor which is linked to
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.
The following return values can occur:
-1 The operation failed, because the underlying BIO is not
of the correct type (suitable for file descriptors).
>=0 The file descriptor linked to ssl.
SSL_set_fd(3), ssl(3) , bio(3)
