Receive an <iovec> of size <n> to the file. | |
Private Attributes | |
ACE_HANDLE | handles_ [2] |
This class is designed to work with select()-based demuxers, such as the ACE_Select_Reactor, which is why it uses sockets on Windows rather than Win32 pipes (which aren't select()'able).
|
Default constructor (does nothing...).
|
|
Open the pipe and initialize the handles.
|
|
Initialize the ACE_Pipe from the read and write handles.
|
|
Default dtor. It doesn't close the handles for you.
|
|
Close down the pipe HANDLEs;.
|
|
Dump the state of the object.
|
|
Open the pipe, setting the buffer size to the maximum.
|
|
Open the pipe and initialize the handles.
|
|
This is the "read" side of the pipe. Note, however, that processes can also write to this handle as well since pipes are bi-directional. |
|
Recv <n> bytes via Win32 ReadFile using overlapped I/O.
|
|
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! |
|
Recv iovecs via <readv>.
|
|
Recv upto <n> bytes in <buf>.
|
|
Recv n bytes, keep trying until n are received.
|
|
Receive an <iovec> of size <n> to the file.
|
|
Send <n> bytes via Win32 WriteFile using overlapped I/O.
|
|
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! |
|
Send iovecs via <writev>.
|
|
send upto <n> bytes in <buf>.
|
|
Send all the <message_block>s chained through their <next> and <cont> pointers. This call uses the underlying OS gather-write operation to reduce the domain-crossing penalty. |
|
Send n bytes, keep trying until n are sent.
|
|
Send an <iovec> of size <n> to the file.
|
|
Send an <iovec> of size <n> to the file. Will block until all bytes are sent or an error occurs. |
|
This is the "write" side of the pipe. Note, however, that processes can also read to this handle as well since pipes are bi-directional. |
