Lots of hacking to make a very simple "ls" utility. I added a dead-simple malloc that only allows allocations < 4096 bytes. It just forwards the request to mmap() every time. I also added simplified versions of opendir() and readdir(). 2018-10-24 10:43:52 +00:00			`#pragma once`

A bunch of LibC boilerplate stuff added while trying to get figlet to build. 2018-10-31 01:09:11 +00:00			`#include <sys/cdefs.h>`

Add some basic signal support. It only works for sending a signal to a process that's in userspace code. We implement reception by synthesizing a PUSHA+PUSHF in the receiving process (operating on values in the TSS.) The TSS CS:EIP is then rerouted to the signal handler and a tiny return trampoline is constructed in a dedicated region in the receiving process. Also hacked up /bin/kill to be able to send arbitrary signals (kill -N PID) 2018-11-06 09:46:40 +00:00			`void* malloc(size_t) __MALLOC;`

Canonicalize the path used by sh. With a bunch of LibC work to support the feature. LibC now initializes AK::StringImpl by default. It's now fine to use AK in LibC/Userland! :^) 2018-10-28 08:36:21 +00:00			`void* calloc(size_t nmemb, size_t);`

Enough compatibility work to make figlet build and run! I ran out of steam writing library routines and imported two BSD-licensed libc routines: sscanf() and getopt(). I will most likely rewrite them sooner or later. For now I just wanted to see figlet running. 2018-10-31 16:50:43 +00:00			`char* getenv(const char* name);`

More LibC portability work while trying to get figlet building. 2018-10-31 09:14:56 +00:00
