There is no advisory locking, only mandatory locking.

Opa.
But why? If I'm not very wrong, Windows has its own advisory locking
API. Why is it not used?
P.S.
I have forgot to say: this behavour is related to all versions op PHP:
php4 and php5 too.

flock() is mandatory under winNT and it's derivatives.
This is a documentation bug.

Description:
------------
This code does not work on Windows:
<?
$f1 = fopen("/tmp/a", "a+b");
flock($f1, LOCK_SH);
$f2 = fopen("/tmp/a", "r+b");
fwrite($f2, "test");
?>
It creates zero-length file. On Linux everything is OK.
If I delete flock() or call flock($f1, LOCK_UN) just after first
flock(), all works correctly.
Flock() is ADVISORY lock, but it works as mandatory lock. Bad luck.
Reproduce code:
---------------
$f1 = fopen("/tmp/a", "a+b");
flock($f1, LOCK_SH);
$f2 = fopen("/tmp/a", "r+b");
fwrite($f2, "test");
Expected result:
----------------
Create non-empty file.
Actual result:
--------------
Creates empty file.
