</pre> Linux/Unix byte locking is advisory (meaning that one lock can block another lock, but it can't block a read).
Win32locking is mandatory (at least in the most portable form) so a lock blocks a reader. To avoid that problem,
youlocka byte that you never intend to read (that is, you lock a byte past the end of the file). Locking past the
end-of-fileis portable to all Unix/Linux systems that I've seen (that way, you can lock a region of a file before you
growthe file).<br /><br /> -- Korry<br /><br />
