In POSIX systems EXCLUSIVE mode is emulated by Harbour so it allow to sync different applications and threads if each of them uses compatible emulation. The fact that POSIX does not support EXCLUSIVE mode only means that nothing stops other applications which do not respect our emulation against opening the same files. This is also true for file servers like SAMBA. If SAMBA does not use compatible EXCLUSIVE mode emulation (and it really doesn't) then it means that both native and remote MS-Windows application can open the same file in EXCLUSIVE mode simultaneously. If application needs EXCLUSIVE mode to synchronize some RDD operations between native POSIX applications executed locally and some remote applications then it should use for remote access HBNETIO. It's not necessary to use HBNETIO for local access. best regards, Przemek _______________________________________________ Harbour mailing list (attachment size limit: 40KB) Harbour@harbour-project.org http://lists.harbour-project.org/mailman/listinfo/harbour
