most functions like this dont have any real libc component ... uClibc will define userspace symbols that merely make a syscall iff the __NR_ exists in the headers if we have __NR_mremap in our unistd.h, we'll automagically get the mremap() symbol in uClibc which simply passes along the args to the kernel -mike - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
