## Detailed Description

Id:
  Asynch_IO.h,v 4.66 2003/07/19 19:04:10 dhinton Exp

This works on Win32 (if defined (ACE_WIN32) && !defined (ACE_HAS_WINCE)) platforms and on POSIX4 platforms with <aio_*> routines (if defined (ACE_HAS_AIO_CALLS))

On Win32 platforms, the implementation of <ACE_Asynch_Transmit_File> and <ACE_Asynch_Accept> are only supported if ACE_HAS_WINSOCK2 is defined or you are on WinNT 4.0 or higher.
