C語言實現獲取內存信息並輸出的實例

實現實例代碼：

headfile.h

#include <stdio.h> 
#include <stdlib.h> 
#include <time.h> 
 
#define TRUE 1 
#define FALSE 0 
#define MAX 10000 
 
typedef int KeyType; 
typedef int OtherType; 
 
typedef struct 
{ 
  KeyType key; 
  OtherType other_data; 
}RecordType; 

seek.cpp

#include "stdafx.h"

#include"WinBase.h" 
#include "Psapi.h" 
 
#pragma once 
#pragma message("Psapi.h --> Linking with Psapi.lib") 
#pragma comment(lib,"Psapi.lib")
