62fa773b27 libc: Add dummy argv 2022-10-21 18:33:06 +02:00

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

b035795eb3 Kernel: Move errno.h and (k)assert.h out of the main include directory
This is mostly so IDEs don't pick them up instead of the userspace headers :)
2022-10-19 17:41:23 +02:00
aa90e4a8d9 libc: Implement freopen() 2022-10-19 17:32:59 +02:00
671f2a2de3 Kernel, libc: Implement waitpid()
FIXME: exec() is now doing weird page table stuff. But at least it works, no panics :)
2022-10-18 21:30:52 +02:00
f1bfa6bec8 Build system: more cflags + stripping 2022-10-18 18:28:28 +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.

48f38bdcef libc: More inttypes.h 2022-10-15 16:53:26 +02:00
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

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

2022-10-15 09:52:37 +02:00
1043b0772d Make libc exit with a specific code if program initialization fails

2022-10-14 19:12:40 +02:00
743aedcd49 libc: Implement atexit() and _exit()
exit() now calls registered handlers before calling _exit().
