Allocate new memory about memoryjs

[Rob--]

It's possible to expose any WinAPI functions through a Node Addon, when I get the time I'll expose VirtualAllocEx. Also working on DLL injection though! I'll post an update here when memory allocation has been implemented.

@JohnDeved implemented in v3.2.3 (6e0496c and d778a60).

Not thoroughly tested, but seems to work according to the single test file I added. Use as follows:

const processObject = memoryjs.openProcess('notepad.exe');

const address = memoryjs.virtualAllocEx(
  processObject.handle,
  null,
  0x60,
  memoryjs.MEM_RESERVE | memoryjs.MEM_COMMIT,
  memoryjs.PAGE_EXECUTE_READWRITE,
);

console.log(`Allocated address: 0x${address.toString(16).toUpperCase()}`);

Further documentation can be found in the readme. I highly recommend reading MSDN's VirtualAllocEx documentation.

Sure this is possible. If you want to write shell-code are you also looking for CreateRemoteThread functionality to execute the injected assembly?

That would be cool!
I just wanted to make a godmode patch in the game i was testing this with and i noticed i was running out of space for the opcode.

Great! I'll be looking forward to it!
