1278cec065 VFS: Add a 'type' flag to Nodes, implement EISDIR 2022-10-11 17:48:11 +02:00
da2ede3450 Kernel, libc, userspace: Implement file descriptors
Kernel: Implement a descriptor struct which stores the opened node and read offset, and give each task 8 of those.
Implement three syscalls: sys_read, sys_open and sys_close (sys_write still writes to the console instead of using a fd, for now)
Implement three new errors: ENOENT, EBADF and EMFILE.

libc: Implement the new errors, and the new syscalls in syscall().
Also fix _RETURN_WITH_ERRNO() to set errno correctly, which was making strerror() return null, thus crashing perror().

userspace: make init demonstrate the new file API.

ce6ec3585c Kernel, libc: Add ENOSYS
This error is returned by the kernel/C Library when an attempt is made to use a system call that doesn't exist.
