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.
ACE_SPIPE_Stream::ACE_SPIPE_Stream | ( | void | ) |
Default constructor.
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 | ( | 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 | ( | 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 | ( | void * | buf, |
size_t | len | ||
) | 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 | ( | ACE_Str_Buf * | cntl, |
ACE_Str_Buf * | data, | ||
int * | band, | ||
int * | flags | ||

Recv iovecs via the OS "scatter-read" operation.
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 ACE_Str_Buf * | cntl, |
const ACE_Str_Buf * | data, | ||
int | flags = 0 |

Send cntl and data via STREAM pipes.
ssize_t ACE_SPIPE_Stream::send | ( | const void * | buf, |

Send bytes via STREAM pipes using "band" mode.
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 void * | buf, |
size_t | len | ||

Send bytes via STREAM pipes using "band" mode.
ssize_t ACE_SPIPE_Stream::send | ( | const iovec | iov[], |
int | len | ||

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

Send len bytes, keep trying until len are sent.
ssize_t ACE_SPIPE_Stream::sendv | ( | const iovec | iov[], |
int | len | ||

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.
