c++ Resumir e Suspender Threads [C++]

[NadaMal- 2.855]

Pode ser utilizado para pausar processos para injetar Dll's ou pausar jogos para leitura da memória ,por exemplo.

 

#include <Windows.h>
#include <iostream>
#include <TlHelp32.h>

using namespace std;

#pragma warning(disable:4996)

int GetPID(char* Process_Name)

Como faz pra suspender 1 ou mais threads e nao todas??
