C++根据进程名获取pid（PID最全方案）-创新互联
网络上流行的方法是创建快照：C++ 判断某个程序是否正在运行,存在返回PID
但是，获取360进程的PID是无效的。
解决方案如下：
#include#includeusing namespace std;
long findProcess(string name) {string command = "tasklist|findstr \"" + name + "\">s.tmp";
system(command.data());
ifstream in("s.tmp");
int c;
c = in.get();
if (c == EOF)
{in.close();
system("del s.tmp");
return -1;
}
string i;
int word = 0;
while (in >>i)
{if (word == 1)
{ break;
}
word++;
}
in.close();
system("del s.tmp");
long pid = atoi(i.c_str());
return pid;
} 当然，性能低
真正的解决方案：
#include#include#define STATUS_INFO_LENGTH_MISMATCH ((NTSTATUS)0xC0000004L)
#define NT_SUCCESS(x) ((x) >= 0)
