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 09:52:37 +02:00
1043b0772d
Make libc exit with a specific code if program initialization fails
...
Now you know, if a program exits with code -127 it's libc's fault :)
2022-10-14 21:26:46 +02:00
d5bc87099f
libc: #define STDOUT_FILENO and STDERR_FILENO
...
Still missing stdin >.<

2022-10-14 19:12:40 +02:00
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!! :)
2022-10-12 20:41:55 +02:00
