Detailed Description

Defines the methods for the ACE socket wrapper I/O routines described below.

If timeout == 0, then the call behaves as a normal send/recv call, i.e., for blocking sockets, the call will block until action is possible; for non-blocking sockets, -1 will be returned with errno == EWOULDBLOCK if no action is immediately possible. If timeout != 0, the call will wait until the relative time specified in *timeout elapses. Errors are reported by -1 and 0 return values. If the operation times out, -1 is returned with errno == ETIME. If it succeeds the number of bytes transferred is returned. Methods with the extra flags argument will always result in send getting called. Methods without the extra flags argument will result in send getting called on Win32 platforms, and write getting called on non-Win32 platforms.

Member Function Documentation

void ACE_SOCK_IO::dump ( void  ) const

Dump the state of an object.

ssize_t ACE_SOCK_IO::recv ( void *  buf,
size_t  n,
int  flags,
const ACE_Time_Value timeout = 0 
) const
inline

Recv an n byte buffer from the connected socket.

ssize_t ACE_SOCK_IO::recv ( void *  buf,
size_t  n,
const ACE_Time_Value timeout = 0 
) const
inline

Recv an n byte buffer from the connected socket.

ssize_t ACE_SOCK_IO::recv ( size_t  n,
  ... 
) const

Recv n varargs messages to the connected socket.

ssize_t ACE_SOCK_IO::recv ( void *  buf,
size_t  n,
ACE_OVERLAPPED overlapped 
) const
inline

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

ssize_t ACE_SOCK_IO::recvv ( iovec  iov[],
int  n,
const ACE_Time_Value timeout = 0 
) const
inline

Recv an <iovec> of size n from the connected socket.

ssize_t ACE_SOCK_IO::recvv ( iovec *  io_vec,
const ACE_Time_Value timeout = 0 
) const

Allows a client to read from a socket without having to provide a buffer to read. This method determines how much data is in the socket, allocates a buffer of this size, reads in the data, and returns the number of bytes read. The caller is responsible for deleting the member in the <iov_base> field of io_vec using delete [] io_vec->iov_base.

ssize_t ACE_SOCK_IO::send ( const void *  buf,
size_t  n,
int  flags,
const ACE_Time_Value timeout = 0 
) const
inline

Send an n byte buffer to the connected socket.

ssize_t ACE_SOCK_IO::send ( const void *  buf,
size_t  n,
const ACE_Time_Value timeout = 0 
) const
inline

Send an n byte buffer to the connected socket.

ssize_t ACE_SOCK_IO::send ( size_t  n,
  ... 
) const

Send n varargs messages to the connected socket.

ssize_t ACE_SOCK_IO::send ( const void *  buf,
size_t  n,
ACE_OVERLAPPED overlapped 
) const
inline

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

ssize_t ACE_SOCK_IO::sendv ( const iovec  iov[],
int  n,
const ACE_Time_Value timeout = 0 
) const
inline

Send an iovec of size n to the connected socket.
