6d7a8a0d0b
libc: Add very basic strtoul()
...
As well as returning NULL in getenv() instead of aborting.
2022-10-21 18:32:46 +02:00
bf026d0dea
libc: Add bad time() function
...
It's just an alias for clock(). Which is not good. But it's a stub, that's the point.
2022-10-21 18:32:01 +02:00

...
Now, fork() and exec() are both implemented. More POSIX-y, thus spawn can be removed.

2022-10-17 18:43:35 +02:00
9b39d618de
Kernel, libc: Implement spawn()
...
This function is a Luna alternative to fork() and exec().
Why? Simply because I can't figure out for the life of me how to implement a working fork().
So meanwhile, we have spawn() as a replacement. exec() still exists, though.
2022-10-16 18:48:35 +02:00

Replace the rand() which reads from /dev/random with a Mersenne PRNG.
...
Much better now.
Also, it is seeded by reading from /dev/random at startup. Not sure if that's the best idea, but we'll see.
2022-10-15 16:46:54 +02:00

2022-10-15 13:21:22 +02:00

Kernel, libc: Remove the rand() system call
...
That's why we now have a VFS and a /dev pseudo-filesystem. To provide that kind of things.
Remember, everything is a file!!
The new way to ask the kernel for random numbers is to read from /dev/random.
2022-10-15 13:04:48 +02:00

2022-10-15 09:52:37 +02:00
d5bc87099f
libc: #define STDOUT_FILENO and STDERR_FILENO

2022-10-14 19:23:14 +02:00
3b83d7ccaf

743aedcd49
libc: Implement atexit() and _exit()
...

2022-10-12 17:45:58 +02:00
edda41a7bb
libc: Implement fseek(), ftell() and rewind()
...
