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_INLINE 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

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 shut down.

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.
