Function Documentation

ACE_BEGIN_VERSIONED_NAMESPACE_DECL ACE_INLINE int ACE_OS::fcntl (  ACE_HANDLE  handle, int  cmd, long  arg = 0 )

ACE_HANDLE ACE_OS::open (  const wchar_t *  filename, int  mode, int  perms = ACE_DEFAULT_OPEN_PERMS, LPSECURITY_ATTRIBUTES  sa = 0 )

ACE_BEGIN_VERSIONED_NAMESPACE_DECL ACE_HANDLE ACE_OS::open (  const char *  filename, int  mode, int  perms = ACE_DEFAULT_OPEN_PERMS, LPSECURITY_ATTRIBUTES  sa = 0 )

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.
