8eb986df63 libc: Add program_invocation_name
This is a GNU extension, but I'm fine with adding it to libc.
It's guarded by the _GNU_SOURCE feature test macro anyways.

As well as ino_t, which I forgot in the fstat() commit :)
2022-10-21 18:34:01 +02:00
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

87ef210759 Kernel, libc: Remove spawn()
Now, fork() and exec() are both implemented. More POSIX-y, thus spawn can be removed.
2022-10-17 19:55:01 +02:00
e7522c21ca libc: Document fork() 2022-10-17 18:56:04 +02:00
64f5078494 Kernel, libc: Implement fork()
This time for real.

Also, add a new per-user-task virtual address allocator (UserHeap), so that mmap'ed pages are in user range and can be copied.
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.

45afd3e243 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
18f1f8b7ca Add VERY HACKY rand() implementation. 2022-10-15 16:31:08 +02:00

2395c7a871 libc: Implement _Exit
Exactly the same as _exit, but in stdlib.h instead of unistd.h
2022-10-15 14:02:10 +02:00
b1739f7f0d libc: Add support for the new clock() system call 2022-10-15 13:21:22 +02:00
3a9dddaa57 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

3e2a4276e9 libc: Add memcmp() and memmove()
Those were there since forever in the kernel, but they haven't been added to libc until now.
2022-10-15 12:23:37 +02:00
