Member Function Documentation

int ACE_UPIPE_Stream::close

(

void

)

Shut down the UPIPE and release resources.

Reimplemented from ACE_SPIPE.

int ACE_UPIPE_Stream::control	(	int	cmd,
		void *	val
	)		const

Perform control operations on the UPIPE_Stream.

Reimplemented from ACE_IPC_SAP.

void ACE_UPIPE_Stream::dump

(

void

)

const

Dump the state of an object.

Reimplemented from ACE_SPIPE.

ACE_HANDLE ACE_UPIPE_Stream::get_handle ( void  ) const

inline

Return the underlying I/O handle.

Reimplemented from ACE_IPC_SAP.

int ACE_UPIPE_Stream::get_remote_addr

(

ACE_UPIPE_Addr &

remote_sap

)

const

Return the remote address we are connected to.

int ACE_UPIPE_Stream::recv	(	ACE_Message_Block *&	mb_p,
		ACE_Time_Value *	timeout = 0
	)

Recv a message from the message queue. Returns -1 on error, else 0.

ssize_t ACE_UPIPE_Stream::recv	(	char *	buffer,
		size_t	n,
		ACE_Time_Value *	timeout = 0
	)

Recv a buffer of upto n bytes from the message queue. Returns -1 on error, else number of bytes read.

ssize_t ACE_UPIPE_Stream::recv_n	(	char *	buffer,
		size_t	n,
		ACE_Time_Value *	timeout = 0
	)

Recv a buffer of exactly n bytes from the message queue. Returns -1 on error, else the number of bytes read.

int ACE_UPIPE_Stream::send	(	ACE_Message_Block *	mb_p,
		ACE_Time_Value *	timeout = 0
	)

Send a message through the message queue. Returns -1 on error, else 0.

ssize_t ACE_UPIPE_Stream::send	(	const char *	buffer,
		size_t	n,
		ACE_Time_Value *	timeout = 0
	)

Send a buffer of n bytes through the message queue. Returns -1 on error, else number of bytes sent.

ssize_t ACE_UPIPE_Stream::send_n	(	const char *	buffer,
		size_t	n,
		ACE_Time_Value *	timeout = 0
	)

Send a buffer of exactly n bytes to the message queue. Returns -1 on error, else number of bytes written (which should == n).

ACE_UPIPE_Stream::ACE_ALLOC_HOOK_DECLARE

Declare the dynamic allocation hooks.

Reimplemented from ACE_SPIPE.

ACE_Message_Block* ACE_UPIPE_Stream::mb_last_

private

To hold the last ACE_Message_Block read out of the stream. Thus allowing subsequent reads from one ACE_Message_Block

int ACE_UPIPE_Stream::reference_count_

private

Keep track of whether the sender and receiver have both shutdown.

ACE_UPIPE_Addr ACE_UPIPE_Stream::remote_addr_

private

Address of who we are connected to.

MT_Stream ACE_UPIPE_Stream::stream_

private

Stream component used by the UPIPE_Acceptor and UPIPE_Connector to link together two UPIPE_Streams.
