c++ map: 当map的value是void*指针

#include <iostream>
#include <map>
#include <vector>

using namespace std;

//key is: pid,cpuseq
struct st_syscall {
	int min;
};

//key is: pid,cpuseq
struct st_pagfalt {
	int max;
};

int type1()
{
	struct st_syscall st1 = {100};
	struct st_pagfalt st2 = {200};

	map<int, struct st_syscall> mp_syscall;
	map<int, struct st_pagfalt> mp_pagfalt;

	mp_syscall.insert(make_pair(1, st1));
	mp_pagfalt.insert(make_pair(1, st2));

	return 0;
}

int type2()
{
	struct st_syscall st1 = {100};
	void *pst1 = (void *)&st1;

	struct st_pagfalt st2 = {200};

	map<int, void*> mp_all;
	mp_all.insert(make_pair(1, pst1));

	return 0;
}

int main()
{

	type1();
	type2();

	return 0;

}
