Are the _get_osfhandle() and _open_osfhandle() functions available in older versions of Windows? (e.g. Windows '98?).

According to MSDN [1], it is. But then I have no idea how accurate MSDN is. :) MSDN also shows _get_osfhandle() as returning an int but on my MSVC 2005 io.h I see it returning an intptr_t.

A problem with Windows API documentation is that it seems that the same APIs don't necessarily work identically across Windows versions.

Well, they're tied to the C runtime library and I also just checked MSVC 2003 and it also shows _get_osfhandle() returning an intptr_t. The issue is whether anyone still compiles libtiff in older MSVC versions (ie. version 6 or lower).

Hmm, I just checked a somewhat old distribution of MinGW (32-bit) and that has _get_osfhandle() returning a long. I'll keep that in mind.
