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.

| ||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. |
