NAME

6       SSL_set_fd - connect the SSL object with a file descriptor
7

SYNOPSIS

9        #include <openssl/ssl.h>
10
11        int SSL_set_fd(SSL *ssl, int fd);
12        int SSL_set_rfd(SSL *ssl, int fd);
13        int SSL_set_wfd(SSL *ssl, int fd);
14

DESCRIPTION

16       SSL_set_fd() sets the file descriptor fd as the input/output facility
17       for the TLS/SSL (encrypted) side of ssl. fd will typically be the
18       socket file descriptor of a network connection.
19
20       When performing the operation, a socket BIO is automatically created to
21       interface between the ssl and fd. The BIO and hence the SSL engine
22       inherit the behaviour of fd. If fd is non-blocking, the ssl will also
23       have non-blocking behaviour.
24
25       If there was already a BIO connected to ssl, BIO_free() will be called
26       (for both the reading and writing side, if different).
27
28       SSL_set_rfd() and SSL_set_wfd() perform the respective action, but only
29       for the read channel or the write channel, which can be set
30       independently.

RETURN VALUES

34

36
37       1   The operation succeeded.
