The essential code is, #include auto struct flock lck; auto int flc; auto int filedesc; filedesc = open(filename, O_RDWR|O_CREAT, 0666); lck.l_type = F_WRLCK; lck.l_start = 0; lck.l_whence = 0; lck.l_len = 0; flc = fcntl(fildesc, F_SETLK, &lck); The fcntl provides a write lock on Windows NT fine (on both FAT and NTFS) filesystems, but fails (flc == -1) on Windows 95. Can anyone help me on this? Many Regards, Ian Collins - For help on using this list (especially unsubscribing), send a message to "gnu-win32-request@cygnus.com" with one line of text: "help".
