Not to my knowledge. On windows, there is only CreateProcess
(http://msdn.microsoft.com/en-us/library/ms682425.aspx). That doesn't
resemble the behavior of fork or exec at all. Basically, there is no
fork, windows favors threading models. The only thing inheritable are
handles, which doesn't include locked portions of a file.
The LockFileEx docs state:
"If a process terminates with a portion of a file locked or closes a
file that has outstanding locks, the locks are unlocked by the operating
system."
