typedef ACE_INET_Addr ACE_SOCK_Dgram::PEER_ADDR

Constructor & Destructor Documentation

ACE_SOCK_Dgram::ACE_SOCK_Dgram ( void )

inline

Default constructor.

ACE_SOCK_Dgram::ACE_SOCK_Dgram	(	const ACE_Addr &	local,
		int	protocol_family = `ACE_PROTOCOL_FAMILY_INET`,
		int	protocol = `0`,
		int	reuse_addr = `0`
	)

This is a BSD-style method (i.e., no QoS) for initiating a socket dgram that will accept datagrams at the <local> address.

ACE_SOCK_Dgram::ACE_SOCK_Dgram	(	const ACE_Addr &	local,
		int	protocol_family,
		int	protocol,
		ACE_Protocol_Info *	protocolinfo,
		ACE_SOCK_GROUP	g = `0`,
		u_long	flags = `0`,
		int	reuse_addr = `0`
	)

This is a QoS-enabed method for initiating a socket dgram that will accept datagrams at the <local> address. The qos_params are passed to <ACE_OS::join_leaf>.

ACE_SOCK_Dgram::~ACE_SOCK_Dgram ( void )

inline

Default dtor.

Member Function Documentation

void ACE_SOCK_Dgram::dump ( void ) const

Dump the state of an object.

int ACE_SOCK_Dgram::get_remote_addr ( ACE_Addr & ) const

private

Do not allow this function to percolate up to this interface...

int ACE_SOCK_Dgram::make_multicast_ifaddr	(	ip_mreq *	mreq,
		const ACE_INET_Addr &	mcast_addr,
		const ACE_TCHAR *	net_if
	)

protected

Create a multicast addr/if pair, in format useful for system calls. If mreq param is NULL, just verify the passed addr/interface specs.

int ACE_SOCK_Dgram::make_multicast_ifaddr6	(	ipv6_mreq *	mreq,
		const ACE_INET_Addr &	mcast_addr,
		const ACE_TCHAR *	net_if
	)

protected

Create a multicast addr/if pair, in format useful for system calls. If mreq param is NULL, just verify the passed addr/interface specs.

int ACE_SOCK_Dgram::open	(	const ACE_Addr &	local,
		int	protocol_family = `ACE_PROTOCOL_FAMILY_INET`,
		int	protocol = `0`,
		int	reuse_addr = `0`
	)

This is a BSD-style method (i.e., no QoS) for initiating a socket dgram that will accept datagrams at the <local> address.

int ACE_SOCK_Dgram::open	(	const ACE_Addr &	local,
		int	protocol_family,
		int	protocol,
		ACE_Protocol_Info *	protocolinfo,
		ACE_SOCK_GROUP	g = `0`,
		u_long	flags = `0`,
		int	reuse_addr = `0`
	)

This is a QoS-enabed method for initiating a socket dgram that will accept datagrams at the <local> address. The qos_params are passed to <ACE_OS::join_leaf>.

ssize_t ACE_SOCK_Dgram::recv	(	void *	buf,
		size_t	n,
		ACE_Addr &	addr,
		int	flags = `0`
	)		const

inline

Receive an n byte buf from the datagram socket (uses <recvfrom(3)>).

ssize_t ACE_SOCK_Dgram::recv	(	iovec *	io_vec,
		ACE_Addr &	addr,
		int	flags = `0`,
		const ACE_Time_Value *	timeout = `0`
	)		const

Allows a client to read from a socket without having to provide a buffer to read. This method determines how much data is in the socket, allocates a buffer of this size, reads in the data, and returns the number of bytes read. The caller is responsible for deleting the member in the <iov_base> field of <io_vec> using the ``delete []'' syntax.

ssize_t ACE_SOCK_Dgram::recv	(	iovec	iov[],
		int	n,
		ACE_Addr &	addr,
		int	flags = `0`
	)		const

Recv an <iovec> of size n to the datagram socket (uses <recvmsg(3)>).

ssize_t ACE_SOCK_Dgram::recv	(	void *	buf,
		size_t	n,
		ACE_Addr &	addr,
		int	flags,
		const ACE_Time_Value *	timeout
	)		const

Wait up to timeout amount of time to receive a datagram into buf. The ACE_Time_Value indicates how long to blocking trying to receive. If timeout == 0, the caller will block until action is possible, else will wait until the relative time specified in *timeout elapses). If <recv> times out a -1 is returned with errno == ETIME. If it succeeds the number of bytes received is returned.

ssize_t ACE_SOCK_Dgram::recv	(	iovec	buffers[],
		int	buffer_count,
		size_t &	number_of_bytes_recvd,
		int &	flags,
		ACE_Addr &	addr,
		ACE_OVERLAPPED *	overlapped,
		ACE_OVERLAPPED_COMPLETION_FUNC	func
	)		const

inline

Recv <buffer_count> worth of buffers from addr using overlapped I/O (uses <WSARecvFrom>). Returns 0 on success.

ssize_t ACE_SOCK_Dgram::recv	(	void *	buf,
		size_t	n,
		ACE_Addr &	addr,
		int	flags,
		ACE_OVERLAPPED *	overlapped,
		ACE_OVERLAPPED_COMPLETION_FUNC	func
	)		const

inline

Receive an n byte buf from the datagram socket (uses <WSARecvFrom>).

ssize_t ACE_SOCK_Dgram::send	(	const void *	buf,
		size_t	n,
		const ACE_Addr &	addr,
		int	flags = `0`
	)		const

inline

Send an n byte buf to the datagram socket (uses <sendto(3)>).

ssize_t ACE_SOCK_Dgram::send	(	const iovec	iov[],
		int	n,
		const ACE_Addr &	addr,
		int	flags = `0`
	)		const

Send an <iovec> of size n to the datagram socket (uses <sendmsg(3)>).

ssize_t ACE_SOCK_Dgram::send	(	const void *	buf,
		size_t	n,
		const ACE_Addr &	addr,
		int	flags,
		const ACE_Time_Value *	timeout
	)		const

Wait up to timeout amount of time to send a datagram to buf. The ACE_Time_Value indicates how long to blocking trying to receive. If timeout == 0, the caller will block until action is possible, else will wait until the relative time specified in *timeout elapses). If <send> times out a -1 is returned with errno == ETIME. If it succeeds the number of bytes sent is returned.

ssize_t ACE_SOCK_Dgram::send	(	const iovec	buffers[],
		int	buffer_count,
		size_t &	number_of_bytes_sent,
		int	flags,
		const ACE_Addr &	addr,
		ACE_OVERLAPPED *	overlapped,
		ACE_OVERLAPPED_COMPLETION_FUNC	func
	)		const

inline

Send <buffer_count> worth of buffers to addr using overlapped I/O (uses <WSASendTo>). Returns 0 on success.

ssize_t ACE_SOCK_Dgram::send	(	const void *	buf,
		size_t	n,
		const ACE_Addr &	addr,
		int	flags,
		ACE_OVERLAPPED *	overlapped,
		ACE_OVERLAPPED_COMPLETION_FUNC	func
	)		const

inline

Send an n byte buf to the datagram socket (uses <WSASendTo>).

int ACE_SOCK_Dgram::set_nic	(	const ACE_TCHAR *	net_if,
		int	addr_family = `AF_UNSPEC`
	)

Set NIC to use as multicast interface.

int ACE_SOCK_Dgram::shared_open	(	const ACE_Addr &	local,
		int	protocol_family
	)

protected

Open is shared by this and by <LSOCK_Dgram>.
