namespace  ACE_OS

This namespace defines an OS independent programming API that shields developers from nonportable aspects of writing efficient system programs on Win32, POSIX and other versions of UNIX, and various real-time operating systems.

int ACE_OS::fcntl (ACE_HANDLE handle, int cmd, long arg=0)
ACE_Export ACE_HANDLE ACE_OS::open (const char *filename, int mode, mode_t 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.
