Yep, strnchr. > What if gcc does it inline in some future version? Not sure what it has to do with that. The #ifdef __HAVE_ARCH_* stuff is that architectures with crazy enough hackers can add assembly optimized functions if they want. But it clearly doesn't make any sense with this function (in fact it doesn't make much sense with any string function except memset/memcpy), so better not encourage it. -Andi
