f50017912d libc: Implement atoi(), atol() and atoll() 2022-10-15 14:02:24 +02:00
2395c7a871 libc: Implement _Exit
Exactly the same as _exit, but in stdlib.h instead of unistd.h

8398b2e2e4 libc: Change bits/macros.h to use a __lc_ prefix for internal macros
That way, we don't pollute user programs with our own 'noreturn' and 'deprecated' macros

743aedcd49 libc: Implement atexit() and _exit()
exit() now calls registered handlers before calling _exit().

And initialize_libc() can now register a handler to close stdout and stderr on program termination!! :)

ffc223c2cf libc: Document functions in stdlib.h
Also, add prototypes for calloc() and realloc(), which were already implemented but not in the header.

f83a6ace51 Kernel, libc: Add support for providing a status code to exit()
The exit() libc function already accepted an integer, but didn't pass it on to the kernel since we had no mechanism for it to do that.
Now, the kernel stores a task's exit status to display it later (and in the future, return it to userspace via wait()/waitpid())

dae2ff8d50 Add mmap and munmap syscalls, and thus, add malloc and free to libc!! (yet again, thanks to the wonderful liballoc) 2022-10-02 20:45:04 +02:00
