Right now, only the framebuffer supports this system call, to query its dimensions.

Kernel: Remove the paint() system call
...
That was a very old one from back in the old days. Now that the framebuffer is finally a device file,
and it can be memory-mapped by user programs for more performance,
this syscall is MORE than obsolete.

Kernel, libc: Fix a big bug in printf()
...
Every time printf flushes the buffer to us in sprintf() or snprintf(), we call strncat to append the data.
But we want to start from the beginning in the first flush. What if there was data already there?
Well, we just append to the old data. Which is not good, and breaks snprintf()'s maximum size policy.
This fix sets the first byte of str to NULL, to avoid this.

endpwent: Close all opened instances of /etc/passwd, including those used by getpwuid() and getpwnam()
2022-10-28 21:02:55 +02:00
7d0e442cde
libc: Add /etc/passwd and the pwd.h API
...
getpwent, getpwnam, getpwuid... they may have been a pain to implement but once they work they're awesome :)
Right now passwords are stored in plaintext in the world-readable passwd file, which is not good.
But I don't have any sort of hashing implemented so it'll stay that way for now.

libc: Do not use the heavy variadic syscall() function for wrappers
...
That function is meant more for user programs, and should still be rarely used, since it's not portable.
Instead, we already know the number of arguments. We just call __lc_fast_syscallN, which also sets errno.
