libc: Implement getuid, geteuid, getgid, getegid
2022-10-28 17:24:28 +02:00
7d20c507b1
Kernel, libc, userspace: Implement command-line arguments (argv)
...
The only thing missing now is for sh to pass them on.

Kernel, libc: Add isatty() and F_ISTTY to fcntl()

libc: Add stdin
...
Aka keyboard :)

Kernel, libc: Rename gettid() to getpid() and move it to unistd.h
2022-10-17 20:08:44 +02:00
e7522c21ca
libc: Document fork()
2022-10-17 18:56:04 +02:00
6507146c60
libc: Add Luna-specific limits
2022-10-15 14:31:55 +02:00
1e86acd4c0
libc: Implement fcntl(F_DUPFD) and dup()
2022-10-15 11:16:34 +02:00
8398b2e2e4
libc: Change bits/macros.h to use a __lc_ prefix for internal macros
...
That way, we don't pollute user programs with our own 'noreturn' and 'deprecated' macros
2022-10-15 09:52:37 +02:00
d5bc87099f
libc: #define STDOUT_FILENO and STDERR_FILENO
...
Still missing stdin >.<

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
531afc3d6f
libc: Add support for the new exec() system call
...
execv() is a temporary wrapper that ignores the second parameter, while execve() and execvp() still error out.

4a5db1dca7
libc: Add lseek()
2022-10-12 15:37:29 +02:00

libc: Document the functions in unistd.h
2022-10-12 11:02:18 +02:00
12cf37d0a7
Kernel/syscalls: Modify sys_write to accept a file descriptor and write to it
...
Previously, sys_write only wrote to the tty. Now, it uses the VFS interface, as it should.
2022-10-11 21:06:12 +02:00
9e0bd39964
libc: Implement wrappers for sys_{open,read,write}
...
read() and close() are in unistd.h, but open() in fnctl.h.
I thought only the definitions for O_SOMETHING were in fnctl.h, but it is as it is.
Don't know why, but let's not anger the Unix gods.
The FILE* C API is pending as well.

Add a proper syscall() function to unistd.h
