Note that this is only the kernel side. I'm not sure what the userland interface will look like. It may be that each feature gains a new sysconf(3) constant rather than adding a new 'feature_present(const char *)' function. Also, I went ahead and put this into sys/sysctl.h rather than a new header because it was only 2 lines of code. -- John Baldwin _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/cvs-all To unsubscribe, send any mail to "[EMAIL PROTECTED]"
