C0deH4cker / hacky.c

Created September 19, 2013 08:00

Hackiest preprocessor macros I may have ever written, yet they surprisingly work for every test case I've thrown at them. Enjoy ;)

Run this on a Mac with an iPhone plugged in and then view a video snap. It will be saved to the current directory. To stop, press Control-C. Requires iFuse. Works without a jailbreak. Clearly not affiliated with Snapchat in any way.

	#!/usr/bin/env python

	import sys, os
	import subprocess
	from shutil import copyfile


	def main():
	mnt = os.path.expanduser("~/mnt")
	snap = mnt + "/snapchat"

Created January 15, 2015 20:52

Example for parsing a mach-o using the ITERCMDS macro (best thing ever!)

	#include <stdio.h>
	#include <stdlib.h>
	#include <stdbool.h>
	#include <stdint.h>
	#include <unistd.h>
	#include <fcntl.h>

	/* Get the next load command from the current one */

C0deH4cker / macho_extractor.c

Last active November 2, 2023 14:47

Program that will extract a segment from a mach-o file. Should even work on Linux/BSD/UNIX?

	#include <stdio.h>
	#include <stdlib.h>
	#include <stdbool.h>
	#include <stdint.h>
	#include <string.h>
	#include <unistd.h>
	#include <fcntl.h>
	#include <sys/mman.h>

	/* For supporting Linux and other systems that don't have mach-o headers */

C0deH4cker / with.h

Created June 10, 2015 08:34

Python's with statement, implemented in C++ via macros

	// Just like C#'s using statement and Python's with statement.
	// This allows use of a resource within a code block, after which
	// the declared object's destructor will clean up.
	// There's nothing about `with` that doesn't work in C, but it is
	// pointless in standard C as there are no destructors.
	// Multiple with statements can be nested as well, so it works as
	// you'd expect. If for some bizarre reason you need to put multiple
	// using statements on the same line, I've added another version,
	// defined below as with_inline.
