* @brief Defines an active connection factory for the ACE_FILE wrappers.
*
* Note that the O_APPEND flag is only partly supported on Win32. If
* you specify O_APPEND, then the file pointer will be positioned at
* the end of the file initially during open, but it is not
* re-positioned at the end prior to each write, as specified by
* POSIX. This is generally good enough for typical situations, but
* it is ``not quite right'' in its semantics.
