Detailed Description

Defines the methods in the ACE_SPIPE_Stream abstraction.

buf is the buffer to write from or receive into. len is the number of bytes to transfer.

The "_n()" I/O methods keep looping until all the data has been transferred. These methods also work for sockets in non-blocking mode i.e., they keep looping on EWOULDBLOCK.

The return values for the "*_n()" methods match the return values from the non "_n()" methods and are specified as follows:

Methods with <iovec> parameter are I/O vector variants of the I/O operations.

The <send> and <revc> operations use "message" semantics rather than "bytestream" semantics.


Member Typedef Documentation


Constructor & Destructor Documentation

ACE_SPIPE_Stream::ACE_SPIPE_Stream ( void   ) 

Default constructor.


Member Function Documentation

void ACE_SPIPE_Stream::dump ( void   )  const

Dump the state of an object.

Reimplemented from ACE_SPIPE.

int ACE_SPIPE_Stream::get_remote_addr ( ACE_SPIPE_Addr remote_sap  )  const [inline]

Obtain the address of whom we are connected with.

ssize_t ACE_SPIPE_Stream::recv ( void *  buf,
size_t  len,
ACE_OVERLAPPED overlapped 
) const [inline]

Recv len bytes via Win32 <ReadFile> using overlapped I/O.

ssize_t ACE_SPIPE_Stream::recv ( size_t  len,
  ... 
) const

This is an interface to readv, that doesn't use the struct iovec explicitly. The ... can be passed as an arbitrary number of (char *ptr, int len) tuples. However, the count N is the *total* number of trailing arguments, *not* a couple of the number of tuple pairs!

ssize_t ACE_SPIPE_Stream::recv ( iovec  iov[],
int  len 
) const [inline]

Recv iovecs via the OS "scatter-read" operation.

ssize_t ACE_SPIPE_Stream::recv ( ACE_Str_Buf cntl,
ACE_Str_Buf data,
int *  band,
int *  flags 
) const [inline]

Recv bytes via STREAM pipes using "band" mode.

ssize_t ACE_SPIPE_Stream::recv ( ACE_Str_Buf cntl,
ACE_Str_Buf data,
int *  flags 
) const [inline]

Recv cntl and data via STREAM pipes.

ssize_t ACE_SPIPE_Stream::recv ( void *  buf,
size_t  len 
) const [inline]

Recv bytes via STREAM pipes using "band" mode.

int ACE_SPIPE_Stream::recv_handle ( strrecvfd &  recvfd  )  const [inline]

Recv an open FD from another process.

int ACE_SPIPE_Stream::recv_handle ( ACE_HANDLE &  handle  )  const [inline]

Recv an open FD from another process.

ssize_t ACE_SPIPE_Stream::recv_n ( void *  buf,
size_t  len 
) const [inline]

Recv len bytes, keep trying until len are received.

ssize_t ACE_SPIPE_Stream::recvv_n ( iovec  iov[],
int  len 
) const [inline]

Receive an <iovec> of size len from the stream.

ssize_t ACE_SPIPE_Stream::send ( const void *  buf,
size_t  len,
ACE_OVERLAPPED overlapped 
) const [inline]

Send len bytes via Win32 <WriteFile> using overlapped I/O.

ssize_t ACE_SPIPE_Stream::send ( size_t  len,
  ... 
) const

Send N char *ptrs and int lengths. Note that the char *'s precede the ints (basically, an varargs version of writev). The count N is the *total* number of trailing arguments, *not* a couple of the number of tuple pairs!

ssize_t ACE_SPIPE_Stream::send ( const iovec  iov[],
int  len 
) const [inline]

Send iovecs via the OS "gather-write" operation.

ssize_t ACE_SPIPE_Stream::send ( const ACE_Str_Buf cntl,
const ACE_Str_Buf data,
int  band,
int  flags 
) const [inline]

Send bytes via STREAM pipes using "band" mode.

ssize_t ACE_SPIPE_Stream::send ( const ACE_Str_Buf cntl,
const ACE_Str_Buf data,
int  flags = 0 
) const [inline]

Send cntl and data via STREAM pipes.

ssize_t ACE_SPIPE_Stream::send ( const void *  buf,
size_t  len 
) const [inline]

Send bytes via STREAM pipes using "band" mode.

int ACE_SPIPE_Stream::send_handle ( ACE_HANDLE  handle  )  const [inline]

Send an open FD to another process.

ssize_t ACE_SPIPE_Stream::send_n ( const void *  buf,
size_t  len 
) const [inline]

Send len bytes, keep trying until len are sent.

ssize_t ACE_SPIPE_Stream::sendv ( const iovec  iov[],
int  len 
) const [inline]

Send an <iovec> of size len to the stream.

ssize_t ACE_SPIPE_Stream::sendv_n ( const iovec  iov[],
int  len 
) const [inline]

Send an <iovec> of size len to the stream. Will block until all bytes are sent or an error occurs.
