Of course, this is a very primitive execvp with hardcoded paths.
If it were decent, it would be integrated into libc instantly.

Kernel, libc: Rename gettid() to getpid() and move it to unistd.h
2022-10-17 20:08:44 +02:00
1e96a45f33
Change 'tid' to 'PID' in init.c
...
I think tasks can be considered programs now. So, gettid() is equal to getpid().
In fact, it should be renamed. And moved to unistd.h. Soon.

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.

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.
