HELP!!!--UNIX file locking.

[Tait Kirkham]

I have a problem which I cannot solve.  I am trying to determine when/if
a file is opened by another process.  I have no control over the other
process so I can't use "lockf".  I cannot find any way to do this
other than getting the inode number and then looking for that number
in a "pstat -i" listing.  My problem with this (besides the obvious) 
is that it won't work over NFS.  Does anyone have any suggestions?
I really need a solution which is system independant.  Is this possible? 
I am currently using Sun 4.0.1 and Xenix.

Any suggestions would be greatly appriciated.

Thanks,

Tait Kirkham
