You cannot use libc functions in the kernel. The kernel does not link against libc. It is not an application, it is a kernel. There are some libc functions which are provided in the kernel; there are other libc functions for which there are similar kernel functions of the same name (e.g. "printf"), and there are some "libc" functions -- quoted because they aren't really there, but you can use them -- that are inlined by the compiler. Programming in the kernel environment is not the same as programming in the normal applications environment (the "POSIX" environment). -- Terry _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
