Detailed Description

Defines a factory that creates new ACE_SSL_SOCK_Stream objects passively.

The ACE_SSL_SOCK_Acceptor has its own ACE_SOCK_Acceptor which handles the basic socket acceptance. This class is a wrapper which adds the SSL acceptance handshake handling. Since SSL is record oriented, some additional steps must be taken after the basic socket acceptance to complete the SSL handshake that takes place at session establishment.

Note:

The user must currently ensure that only one thread services a given SSL session at any given time since some underlying SSL implementations, such as OpenSSL, are not entirely thread-safe or reentrant.

Constructor & Destructor Documentation

ACE_BEGIN_VERSIONED_NAMESPACE_DECL ACE_INLINE ACE_SSL_SOCK_Acceptor::ACE_SSL_SOCK_Acceptor

(

void

)

Default constructor.

ACE_BEGIN_VERSIONED_NAMESPACE_DECL ACE_SSL_SOCK_Acceptor::~ACE_SSL_SOCK_Acceptor

(

void

)

Default destructor.

ACE_INLINE ACE_SSL_SOCK_Acceptor::ACE_SSL_SOCK_Acceptor	(	const ACE_Addr &	local_sap,
		int	reuse_addr = 0,
		int	protocol_family = PF_UNSPEC,
		int	backlog = ACE_DEFAULT_BACKLOG,
		int	protocol = 0
	)

Initiate a passive mode SSL/BSD-style acceptor socket.

Parameters:

local_sap

The address that we're going to listen for connections on. If this is ACE_Addr::sap_any, this socket listens on an the "any" IP address and selects an unused port. To find out what port was selected, call this object's ACE_SOCK::get_local_addr(ACE_Addr&) method upon return.

ACE_INLINE ACE_SSL_SOCK_Acceptor::ACE_SSL_SOCK_Acceptor	(	const ACE_Addr &	local_sap,
		ACE_Protocol_Info *	protocolinfo,
		ACE_SOCK_GROUP	g,
		u_long	flags,
		int	reuse_addr,
		int	protocol_family = PF_UNSPEC,
		int	backlog = ACE_DEFAULT_BACKLOG,
		int	protocol = 0
	)

Initiate a passive-mode QoS-enabled acceptor socket.

Parameters:

local_sap

The address that we're going to listen for connections on. If this is ACE_Addr::sap_any, this socket listens on an the "any" IP address and selects an unused port. To find out what port was selected, call this object's ACE_SOCK::get_local_addr(ACE_Addr&) method upon return.

Member Function Documentation

int ACE_SSL_SOCK_Acceptor::accept	(	ACE_SSL_SOCK_Stream &	new_stream,
		ACE_Addr *	remote_addr = 0,
		ACE_Time_Value *	timeout = 0,
		bool	restart = true,
		bool	reset_new_handle = false
	)		const

Accept a new ACE_SSL_SOCK_Stream connection. On successful return, the socket has been accepted and the SSL handshake has been completed.

Parameters:

new_stream	The ACE_SSL_SOCK_Stream object that will receive the new SSL socket.
remote_addr	Pointer to an ACE_INET_Addr object that will receive the address of the peer that connected.
timeout	The maximum time to wait for the combined socket acceptance and handshake completion. 0 means block forever, a timeout of {0, 0} means poll.
restart	1 means "restart if interrupted," that is, if errno == EINTR.

Returns:

0 if success; -1 for failure (errno contains error code).

int ACE_SSL_SOCK_Acceptor::accept	(	ACE_SSL_SOCK_Stream &	new_stream,
		ACE_Accept_QoS_Params	qos_params,
		ACE_Addr *	remote_addr = 0,
		ACE_Time_Value *	timeout = 0,
		bool	restart = true,
		bool	reset_new_handle = false
	)		const

Accept a new ACE_SSL_SOCK_Stream connection using the RVSP QoS information in qos_params.

Parameters:

new_stream	The ACE_SSL_SOCK_Stream object that will receive the new SSL socket.
remote_addr	Pointer to an ACE_INET_Addr object that will receive the address of the peer that connected.
timeout	The maximum time to wait for the combined socket acceptance and handshake completion. 0 means block forever, a timeout of {0, 0} means poll.
restart	1 means "restart if interrupted," that is, if errno == EINTR.

Returns:

0 if success; -1 for failure (errno contains error code).

ACE_INLINE int ACE_SSL_SOCK_Acceptor::close

(

void

)

Close the listening socket.

Reimplemented from ACE_SOCK.

ACE_INLINE int ACE_SSL_SOCK_Acceptor::open	(	const ACE_Addr &	local_sap,
		int	reuse_addr = 0,
		int	protocol_family = PF_UNSPEC,
		int	backlog = ACE_DEFAULT_BACKLOG,
		int	protocol = 0
	)

Initiate a passive mode SSL/BSD-style acceptor socket.

Parameters:

local_sap

The address that we're going to listen for connections on. If this is ACE_Addr::sap_any, this socket listens on an the "any" IP address and selects an unused port. To find out what port was selected, call this object's ACE_SOCK::get_local_addr(ACE_Addr&) method upon return.

Returns:

0 if success; -1 for failure (errno contains error code).

int ACE_SSL_SOCK_Acceptor::ssl_accept	(	ACE_SSL_SOCK_Stream &	new_stream,
		ACE_Time_Value *	timeout
	)		const [protected]

Complete SSL passive connection establishment.
