.PP
.SH CONSTRUCTOR & DESTRUCTOR DOCUMENTATION
.PP
.SS ACE_DEV_IO::ACE_DEV_IO (void)
.PP
Default constructor.
.PP
.SH MEMBER FUNCTION DOCUMENTATION
.PP
.SS void ACE_DEV_IO::dump (void) const
.PP
Dump the state of an object.
.PP
Reimplemented from \fBACE_DEV\fR.
.SS int ACE_DEV_IO::get_local_addr (\fBACE_DEV_Addr\fR &) const
.PP
Return the local endpoint address.
.PP
.SS int ACE_DEV_IO::get_remote_addr (\fBACE_DEV_Addr\fR &) const
.PP
Return the address of the remotely connected peer (if there is one).
.PP
.SS \fBssize_t\fR ACE_DEV_IO::recv (void * buf, size_t n, \fBACE_OVERLAPPED\fR * overlapped) const
.PP
Recv <n> bytes via Win32 ReadFile using overlapped I/O.
.PP
.SS \fBssize_t\fR ACE_DEV_IO::recv (size_t n, ...) const
.PP
This is an interface to readv, that doesn't use the struct \fBiovec\fR 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!
.SS \fBssize_t\fR ACE_DEV_IO::recv (\fBiovec\fR iov[], size_t n) const
.PP
Recv iovecs via <readv>.
.PP
.SS \fBssize_t\fR ACE_DEV_IO::recv (void * buf, size_t n) const
.PP
Recv upto <n> bytes in <buf>.
.PP
.SS \fBssize_t\fR ACE_DEV_IO::recv_n (void * buf, size_t n) const
.PP
Recv n bytes, keep trying until n are received.
.PP
.SS \fBssize_t\fR ACE_DEV_IO::send (const void * buf, size_t n, \fBACE_OVERLAPPED\fR * overlapped) const
.PP
Send <n> bytes via Win32 WriteFile using overlapped I/O.
.PP
.SS \fBssize_t\fR ACE_DEV_IO::send (size_t n, ...) const
.PP
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!
.SS \fBssize_t\fR ACE_DEV_IO::send (const \fBiovec\fR iov[], size_t n) const
.PP
Send iovecs via <writev>.
.PP
.SS \fBssize_t\fR ACE_DEV_IO::send (const void * buf, size_t n) const
.PP
send upto <n> bytes in <buf>.
.PP
.SS \fBssize_t\fR ACE_DEV_IO::send_n (const void * buf, size_t n) const
.PP
Send n bytes, keep trying until n are sent.

.PP
.SS ACE_DEV_IO::ACE_ALLOC_HOOK_DECLARE
