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

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.

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.

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_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.

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.

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_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).

Member Data Documentation

Declare the dynamic allocation hooks.

Reimplemented from ACE_SPIPE.

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

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

Address of who we are connected to.

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