获取ini文件所有的Sections和Keys

获取ini文件中所有的Sections和Keys，并以pair对的方式存入到vector中

#include <iostream>
#include <windows.h>
#include <string>
#include <vector>
using namespace std;

#define PATH "E:\\vc_code\\parse_ini\\cfg.ini"
int main()

    int num = GetPrivateProfileSectionNames(buff, 1024, PATH);
    size_t startpos = 0;
    for (size_t i = 0; i < num; ++i)
    {
