What is it all about?

klibc is a minimalistic subset of the standard C library developed by H. Peter Anvin. It was developed mainly to be used during the Linux startup process, and it is part of the early user space, i.e. components used during kernel startup, but which do not run in kernel mode. These components do not have access to the standard library (usually glibc) used by normal userspace programs.

Key Features

* Klibc library is optimized for correctness and small size. * Klibc is also technically suitable for embedded software in general, and even some full-featured programmes such as the MirBSD Korn Shell. * Klibc is licensed under the full GPL license, which (unlike LGPL) imposes itself on any code linked with it. (This only applies to klibc as a whole due to embedding some Linux kernel derived files; most of the library source code is actually available under a BSD licence from UCB or the Historical Permission Notice and Disclaimer.) This may limit its applicability to commercial embedded software.
