flock for win32

[RDWest]

hi yall,
    i just joined the list.  i've been fooling with perl scripts for a few months now. 
 
just installing and editing html output mainly...
now i'm studying a coupkle books to write my own (i hope)

question:   i've seen a couple post in some forums about creating a temp 
file for a lock on win32(i know win32 doesn't support FLOCK)

these post had a couple of contradictions about them...

does anyone know a stable way to lock a file on win32?
