Unfortunately, the POSIX committee doesn't agree with >me, and outlawed extra fields in the stat/utime structures. My understanding was that only the utime structure is specifically forbidden to have extras, and for it there wasn't much choice: since it is fed to the kernel, not obtained from it, there is an unsolvable problem of how you (portably!) fill in mysterious non-standard extra fields so that the kernel won't see garbage in them. -- Committees do harm merely by existing. | Henry Spencer at U of Toronto Zoology -Freeman Dyson | henry@zoo.toronto.edu utzoo!henry
