The example is still relevant, say if your program has no OS.

  > The example is still relevant, say if your program has no OS. Not only does it seem unlikely your program would have a terminal output and standard streams without having an OS, bestline still requires a libc. Just open `bestline.c` and you'll find: #include <termios.h> #include <unistd.h> #include <stdlib.h> #include <stdio.h> #include <errno.h> #include <string.h> #include <stdlib.h> #include <ctype.h> #include <sys/stat.h> #include <sys/types.h> #include <sys/ioctl.h> #include <sys/mman.h> #include <unistd.h> #include <setjmp.h> #include <poll.h> #include <assert.h> #include <signal.h> #include <fcntl.h> #include <limits.h>

    You've never used a microcontroller. They are usually shipped with a partial libc that binds fd 0/1 to a USART. Sometimes POSIX threads can be mapped to FreeRTOS calls. Most of the defines can have a null implementation and the core will still work. They just need to be defined.

      You’re not making any sense. If the system provides a libc stub then printf and whatever are not concerns, they’ll just go through the stub. And the message I quoted says literally nothing about µc.
