SSL_set_fd(3)SSL_set_fd(3)NAMESSL_set_fd - Connect the SSL object with a file descriptor
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 );
DESCRIPTION
The SSL_set_fd() function sets the file descriptor fd as the input/out‐
put facility for the TLS/SSL (encrypted) side of ssl. The fd will typi‐
cally be the socket file descriptor of a network connection.
When performing the operation, a socket BIO is automatically created to
interface between the ssl and the fd. The BIO and the SSL engine
inherit the behavior of fd. If fd is non-blocking, the ssl will also
have non-blocking behavior.
If there was already a BIO connected to ssl, the BIO_free() function
will be called (for both the reading and writing side, if different).
The SSL_set_rfd() and SSL_set_wfd() functions perform the respective
action, but only for the read channel or the write channel, which can
be set independently.
RETURN VALUES
The following return values can occur: The operation failed. Check the
error stack to find out why. The operation succeeded.
