-=head1 NAME
-
-SSL_do_handshake - perform a TLS/SSL handshake
-
-=head1 SYNOPSIS
-
- #include <openssl/ssl.h>
-
- int SSL_do_handshake(SSL *ssl);
-
-=head1 DESCRIPTION
-
-SSL_do_handshake() will wait for a SSL/TLS handshake to take place. If the
-connection is in client mode, the handshake will be started. The handshake
-routines may have to be explicitly set in advance using either
-L<SSL_set_connect_state(3)|SSL_set_connect_state(3)> or
-L<SSL_set_accept_state(3)|SSL_set_accept_state(3)>.
-
-=head1 NOTES
-
-The behaviour of SSL_do_handshake() depends on the underlying BIO.
-
-If the underlying BIO is B<blocking>, SSL_do_handshake() will only return
-once the handshake has been finished or an error occurred.
-
-If the underlying BIO is B<non-blocking>, SSL_do_handshake() will also return
-when the underlying BIO could not satisfy the needs of SSL_do_handshake()
-to continue the handshake. In this case a call to SSL_get_error() with the
-return value of SSL_do_handshake() will yield B<SSL_ERROR_WANT_READ> or
-B<SSL_ERROR_WANT_WRITE>. The calling process then must repeat the call after
-taking appropriate action to satisfy the needs of SSL_do_handshake().
-The action depends on the underlying BIO. When using a non-blocking socket,
-nothing is to be done, but select() can be used to check for the required
-condition. When using a buffering BIO, like a BIO pair, data must be written
-into or retrieved out of the BIO before being able to continue.
-
-=head1 RETURN VALUES
-
-The following return values can occur:
-
-=over 4
-
-=item Z<>0
-
-The TLS/SSL handshake was not successful but was shut down controlled and
-by the specifications of the TLS/SSL protocol. Call SSL_get_error() with the
-return value B<ret> to find out the reason.
-
-=item Z<>1
-
-The TLS/SSL handshake was successfully completed, a TLS/SSL connection has been
-established.
-
-=item E<lt>0
-
-The TLS/SSL handshake was not successful because a fatal error occurred either
-at the protocol level or a connection failure occurred. The shutdown was
-not clean. It can also occur of action is need to continue the operation
-for non-blocking BIOs. Call SSL_get_error() with the return value B<ret>
-to find out the reason.
