What is called libc in general is the C runtime library, which provides various ordinary functions and a wrapper between C applications and the OS. Years ago, Linux kernel people developped their own libc because unsatisfied from glibc (the Gnu version of libc) and they called it "libc" which was confusing but this was not for use by the kernel. This library is now abandonned. The kernel itself does not make use of any library at all. The libc is meant for userspace applications written in C. It is easier to interface C runtime to the kernel because the kernel is also written in C. Other languages come with their own runtime library. Ada runtime library interfaces with the libc rather than directly with the kernel, because the most dificult is already done. The most popular versions of libc are glibc, musl, uClibc, dietlibc. -- Didier _______________________________________________ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
