ssize_t send_n (

);
len bytes into buf from handle (uses
the send call). If send blocks for longer than timeout the
number of bytes actually sent is returned with errno == ETIME.
If a timeout does not occur, send_n return len (i.e., the
number of bytes requested to be sent).
ssize_t recv_n (
void *buf,
size_t len,
int flags,
const ACE_Time_Value *timeout
);
len bytes into buf from handle (uses
the ACE::recv_n call). The ACE_Time_Value indicates how long
to blocking trying to receive. If timeout == 0, the caller
will block until action is possible, else will wait until the
relative time specified in *timeout elapses). If recv blocks
for longer than timeout the number of bytes actually read is
returned with errno == ETIME. If a timeout does not occur,
recv_n return len (i.e., the number of bytes requested to be
read).
ssize_t sendv_n (const iovec iov[], size_t n) const;
iovec of size n to the connected socket (uses
ACE::sendv_n). Will block until all bytes are sent or an error
occurs.
ssize_t recvv_n (iovec iov[], size_t n) const;
iovec of size n to the connected socket.
int close_reader (void);
int close_writer (void);
int close (void);
close_writer before doing
the close to avoid losing data).
