exclusive file open at windows and linux

[Leonard]

Hi,
I'm writing a client/server console program for win2k server. This program
have to exclusive open/read/write to a share file on a linux machine.
I'm using _fsopen("\\\\linux\sharefile", "at", _SH_DENYWR).
When i run multiple copies of my program on 1 win2k machine, it does achive
the exclusive open/read/write.
But when i run multiple copies of my program from different win2k machine,
it failed !

Anybody know how to do that ? I need to run the same program at different
win2k machine.

My situation :
MachineA (win2k) -> run myprogram.exe
MachineB (win2k) -> run myprogram.exe
MachineC(linux, fileserver). -> shareFile1.txt

both myprogram.exe may open shareFile1.txt at MachineC at the same time. And
i need to prevent this.
Only 1 guy can access(open/read/write) shareFile1.txt at the same time.

Anybody know how to solve it ?

Thank you very much.

Regards,
Leornard.

_SH_DENYWR only denies writes. The other thing I would check is, if the
file resides on an NT box, does the sharing work (well, _not_ work) as
you expect?
