[Gluster-devel] gluster 2.0.8(7) make error on solaris: flock

[shellcode]

ok, i find some info about my problem
flock is not working on solaris, replacement is lockf
http://man-wiki.net/index.php/3:lockf
.......... 
      int lockf(int fd, int cmd, off_t len);
..........
i fix glusterfsd.c (it's compiling), but i can't find any info how i can 
calculate filesize for "len" arg
i.e. lockf - apply,  test or remove a POSIX lock on a _section_ of an open 
file, and for locking file (not section) we need filesize.
any ideas ?
