[gfarm-discuss:09115] Re: File locking mechanism

[Osamu Tatebe <tatebe@xxxxxxxxxxxxxxxx>]

Hi Jass,

Gfarm v1 does not have byte-level file locking mechanism.  Instead,
O_EXCL is supported.  Complete byte-level file locking might be
supported by Gfarm v2 in the future.

BTW, why do you need complete locking facility?  How do you wan to
use?

Thanks,
Osamu
