/**
* @class ACE_SOCK_IO
*
* @brief Defines the methods for the ACE socket wrapper I/O routines
* described below.
*
* If @a 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 @a timeout != 0, the call will wait until the relative time
* specified in *@a timeout elapses.
* Errors are reported by -1 and 0 return values. If the
* operation times out, -1 is returned with @c errno == ETIME.
* If it succeeds the number of bytes transferred is returned.
* Methods with the extra @a flags argument will always result in
* @c send getting called. Methods without the extra @a flags
* argument will result in @c send getting called on Win32
* platforms, and @c write getting called on non-Win32 platforms.
