Kernel, libc: Add support for querying the framebuffer's scanline via ioctl()
2022-11-03 20:20:22 +01:00
249c79f8a3
Kernel, libc: Add ioctl()
...
Right now, only the framebuffer supports this system call, to query its dimensions.

feab66c0d3
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.

2022-10-23 18:35:32 +02:00
78d72c2f0c
Kernel, libc: Add a getdents() system call
...
This is meant to be a low-level interface to implement dirent.h on top of.
2022-10-23 14:03:46 +02:00
35616993f8
libc: Add div(), ldiv(), and lldiv()

As well as ino_t, which I forgot in the fstat() commit :)
2022-10-21 18:34:01 +02:00
fcf191aa7a
Kernel, libc: Add fstat()
2022-10-21 18:31:09 +02:00

2022-10-15 12:57:14 +02:00
edda41a7bb
libc: Implement fseek(), ftell() and rewind()
...
All three use the new syscall seek() (with its lseek() wrapper in unistd.h)!!
2022-10-12 15:56:03 +02:00

2022-10-12 12:06:45 +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.

Avoid magic numbers

Kernel, libc and userspace: Add basic errno support.
...
Kernel: Add an errno.h header with definitions for each header,
and return those, negated, from syscalls when there is an error.
mmap() returns an invalid address with errno encoded, instead of
returning a negated errno; this address is encoded as ffffffffffffffEE
where EE is errno in hex.
libc: make syscall() return -1 and set errno on error, instead of
returning the raw return value of the system call. Also, add mmap()
and munmap() wrappers in sys/mman.h :).
userspace: make the memeater program show the value of errno
when allocating memory fails.
Things to improve: add perror() and strerror() to make the errno
experience even better! >.<
