mmap/munmap with zero length
i'm wondering why mmap and munmap behave differently when it comes to a length argument of zero. allocating memory with mmap for a zero length file returns a valid pointer to the mapped region. munmap however isn't able to remove a mapping with no length. wouldn't it be better to either forbid this in mmap or to allow it in munmap? cheers. alex _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To...

Re: c question: *printf'ing arrays
Note that %x will only print *one* digit for values smaller than 16, For multi-byte fields, it makes sense to print "0x" first and then iterate. For single-byte values, it's probably a tiny bit faster to go only _once_ through for *printf() family formatter, i.e.: - fprintf(stderr, "\nFixed Value: 0x"); - fprintf(stderr, "%x", hdr->fixed_val); + fprintf(stderr, "\nFixed Value: 0x%x", hdr->fixed_val); Some terminal setups will *not* output the last line if it does not f...

Re: bootstrapping gnat GCC on amd64
Status update: http://gcc.gnu.org/ml/gcc-patches/2009-07/msg00102.html I replied to the last email in the thread but haven't heard back yet. Presumably I'll be maintaining the FreeBSD x86_64 port. I'm about to start work on the FreeBSD port now. _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscribe@freebsd.org"
