=head1 NAME
|
|
|
|
SSL_set_fd - connect the SSL object with a file descriptor
|
|
|
|
=head1 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);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
SSL_set_fd() sets the file descriptor B<fd> as the input/output facility
|
|
for the TLS/SSL (encrypted) side of B<ssl>. B<fd> will typically be the
|
|
socket file descriptor of a network connection.
|
|
|
|
When performing the operation, a B<socket BIO> is automatically created to
|
|
interface between the B<ssl> and B<fd>. The BIO and hence the SSL engine
|
|
inherit the behaviour of B<fd>. If B<fd> is non-blocking, the B<ssl> will
|
|
also have non-blocking behaviour.
|
|
|
|
If there was already a BIO connected to B<ssl>, BIO_free() will be called
|
|
(for both the reading and writing side, if different).
|
|
|
|
SSL_set_rfd() and SSL_set_wfd() perform the respective action, but only
|
|
for the read channel or the write channel, which can be set independently.
|
