virtual int INetStreamSocket::accept ( INetStreamSocket ** )

pure virtual

Accept an incoming connection.

Referenced by ns3::NscTcpSocketImpl::Accept().

Here is the caller graph for this function:

virtual void INetStreamSocket::connect	(	const char *	,
		int
	)

pure virtual

Connect to a remote peer.

Referenced by ns3::NscTcpSocketImpl::Connect().

Here is the caller graph for this function:

virtual void INetStreamSocket::disconnect ( )

pure virtual

Disconnect from a remote peer.

Referenced by ns3::NscTcpSocketImpl::Close(), and ns3::NscTcpSocketImpl::SendPendingData().

Here is the caller graph for this function:

virtual bool INetStreamSocket::get_var	(	const char *	var,
		char *	result,
		int	result_len
	)

inlinevirtual

Optional function used to get variables for this TCP connection.

Note: not implemented

Parameters

var	variable requested
result	result result
result_len	result length

Returns: always false

Definition at line 350 of file sim_interface.h.

virtual int INetStreamSocket::getpeername	(	struct sockaddr *	sa,
		size_t *	salen
	)

inlinevirtual

Get the peer name.

Note: not implemented

Parameters

sa	sockaddr structure to fill
salen	sockaddr structure length

Returns: -1 on error (always returns -1)

Definition at line 325 of file sim_interface.h.

Referenced by ns3::NscTcpSocketImpl::CompleteFork().

Here is the caller graph for this function:

virtual int INetStreamSocket::getsockname	(	struct sockaddr *	sa,
		size_t *	salen
	)

inlinevirtual

Get the socket local name.

Note: not implemented

Parameters

sa	sockaddr structure to fill
salen	sockaddr structure length

Returns: -1 on error (always returns -1)

Definition at line 337 of file sim_interface.h.

Referenced by ns3::NscTcpSocketImpl::CompleteFork(), and ns3::NscTcpSocketImpl::ConnectionSucceeded().

Here is the caller graph for this function:

virtual bool INetStreamSocket::is_connected ( )

pure virtual

Check the connection state.

Returns: true if socket is in connected state

Referenced by ns3::NscTcpSocketImpl::NSCWakeup().

Here is the caller graph for this function:

virtual bool INetStreamSocket::is_listening ( )

pure virtual

Check the listening state.

Returns: true if socket is in listening state

Referenced by ns3::NscTcpSocketImpl::Accept().

Here is the caller graph for this function:

virtual void INetStreamSocket::listen ( int )

pure virtual

Put the socket in Listening state on a port.

Referenced by ns3::NscTcpSocketImpl::Listen().

Here is the caller graph for this function:

virtual void INetStreamSocket::print_state ( FILE * )

pure virtual

Print the socket state.

virtual int INetStreamSocket::read_data	(	void *	buf,
		int *	buflen
	)

pure virtual

Read some data.

Parameters

buf	the buffer to store the data
buflen	buffer length

Returns: the number of data read or -1 on error

Referenced by ns3::NscTcpSocketImpl::ReadPendingData().

Here is the caller graph for this function:

virtual int INetStreamSocket::send_data	(	const void *	data,
		int	datalen
	)

pure virtual

Send some data.

Parameters

data	the data
datalen	data length

Returns: the number of data sent or -1 on error

Referenced by ns3::NscTcpSocketImpl::SendPendingData().

Here is the caller graph for this function:

virtual bool INetStreamSocket::set_var	(	const char *	var,
		const char *	val
	)

inlinevirtual

Optional function used to set variables for this TCP connection.

Note: not implemented

Parameters

var	variable to set
val	value to set

Returns: always false

Definition at line 363 of file sim_interface.h.

virtual int INetStreamSocket::setsockopt	(	char *	optname,
		void *	val,
		size_t	valsize
	)

pure virtual

Set the socket options.

We need to pass the option name in as a string here. The reason for this is that different operating systems you compile on will have different numbers defined for the constants SO_SNDBUF and so on.

Parameters

optname	name of the option
val	option value
valsize	size of the option value

Returns
