spolupraca: NFS server Windows <-> NFS klient UNIX

[Kilian Igor]

Dik. pozrel som na to, ale neviem spravit perlovy skript
s pouzitim fcntl. Dozvedel som sa:
Perl uses the flock function, which may use flock,
lockf, or fcntl under the hood.

Takze som pouzil podla rady na zaciatku scriptu:
use Fcntl qw(:flock);
(to by malo zabezpecit, ze flock pouziva na zamknutie fcntl)

Bohuzial nefunguje to. Prosim napiste mi taky perlovy
script, ktory skutocne pouzije na zamknutie fcntl. Nech
viem aspon jednu stranu problemu odhalit (cize ci je
problem na UNIXe, alebo WIN). Ak to mam dobre, tak tiez
prosim o potvrdenie. Dakujem.
