Detailed Description

Read/Write operations on Devices.


Member Typedef Documentation

typedef ACE_DEV_Addr ACE_DEV_IO::PEER_ADDR
 


Constructor & Destructor Documentation

ACE_DEV_IO::ACE_DEV_IO void   
 

Default constructor.


Member Function Documentation

void ACE_DEV_IO::dump void    const
 

Dump the state of an object.

Reimplemented from ACE_DEV.

int ACE_DEV_IO::get_local_addr ACE_DEV_Addr   addr const
 

Return the local endpoint address.

int ACE_DEV_IO::get_remote_addr ACE_DEV_Addr   addr const
 

Return the address of the remotely connected peer (if there is one).

ASYS_INLINE ssize_t ACE_DEV_IO::recv void *    buf,
size_t    n,
ACE_OVERLAPPED   overlapped
const
 

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

ssize_t ACE_DEV_IO::recv size_t    n,
...   
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!

ASYS_INLINE ssize_t ACE_DEV_IO::recv iovec    iov[],
size_t    n
const
 

Recv iovecs via <readv>.

ASYS_INLINE ssize_t ACE_DEV_IO::recv void *    buf,
size_t    n
const
 

Recv upto <n> bytes in <buf>.

ASYS_INLINE ssize_t ACE_DEV_IO::recv_n void *    buf,
size_t    n
const
 

Recv n bytes, keep trying until n are received.

ASYS_INLINE ssize_t ACE_DEV_IO::send const void *    buf,
size_t    n,
ACE_OVERLAPPED   overlapped
const
 

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

ssize_t ACE_DEV_IO::send size_t    n,
...   
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!

ASYS_INLINE ssize_t ACE_DEV_IO::send const iovec    iov[],
size_t    n
const
 

Send iovecs via <writev>.

ASYS_INLINE ssize_t ACE_DEV_IO::send const void *    buf,
size_t    n
const
 

send upto <n> bytes in <buf>.

ASYS_INLINE ssize_t ACE_DEV_IO::send_n const void *    buf,
size_t    n
const
 

Send n bytes, keep trying until n are sent.
