Syscalls don't have to go through the multiplexer in grab bag calls like prctl, ioctl, etc. And they are more reliably to test for at runtime. An ENOSYS error is unmistakably clear. An EINVAL error, as returned by prctl when encountering an unknown function argument, could also mean the argument isn't valid. That's a common problem of most multiplexer syscalls and a reason why they should be avoided. - -- ➧ Ulrich Drepper ➧ Red Hat, Inc. ➧ 444 Castro St ➧ Mountain View, CA ❖ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) iEYEARECAAYFAkuV2vMACgkQ2ijCOnn/RHTRYgCeJd0O3O71jHtvGhvOG5Ax2oxP I5UAnjujkQBlHxFzXqhsEMavsaVVsEBf =PnMs -----END PGP SIGNATURE----- -- To unsubscribe from this list: send the line "unsubscribe linux-api" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
