I general, the more error checks be better say I!!!

Windows support of POSIX is claimed but I'm sure is limited.  Here's the overview URL:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnucmg/html/ucmglp.asp?frame=true

Chapter 8 of the above describes some limitations for fcntl re POSIX.1, see Table 3:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnucmg/html/UCMGch08.asp?frame=true

Chapter 9 of the above describes fcntl but rewrites it away, see "File and Data Access" link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnucmg/html/UCMGch09.asp?frame=true

The Visual C++ 6.0 Run-Time Library Reference, see "Alphabetic Function Reference" in left frame:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vccore98/HTML/crthm.asp?frame=true
just plain flat out omits "fcntl" function altogether.

If you send me an "fcntl" function prototype and requirements
description, I'll see what's possible using native Win32 API.
