I'd like to get an exclusive lock for a file (it's for debugging purposes).

On Linux there's flock http://linux.die.net/man/1/flock

On BSD i've found lockf http://www.unix.com/man-page/FreeBSD/1/lockf/

When you call CreateFile to open a file, just pass in 0 for dwShareMode.

If this parameter is zero and CreateFile succeeds, the file or device cannot be shared and cannot be opened again until the handle to the file or device is closed.
