C语言实现获取内存信息并输出的实例

C语言实现获取内存信息并输出的实例

实现实例代码：

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 "headfile.h"
#include "windows.h"
#include "conio.h " 

#include"WinBase.h"
#include "Psapi.h" 

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

int Data[MAX]={0}; 

void produceData(int a[],int length)    //给数组生成数据，用于随即查找
{
  time_t t;
  srand(time(&t));
  for (int i=0;i<length;i++)
  {
    a[i]=rand()%length;
  }
} 

void printData(int a[],int length)   //打印数字，到控制台，每五个换一行
{
  for (int i=0;i<length;i++)
  {
    printf("%8d",a[i]);
    if (0==i%5)
    {
      printf("\n");
    }
  }
} 

double showMemoryInfo()
{
  double MemorySize;         //单位MB
  HANDLE handle=GetCurrentProcess();   

  PROCESS_MEMORY_COUNTERS pmc;
  GetProcessMemoryInfo(handle,&pmc,sizeof(pmc));
  MemorySize=pmc.WorkingSetSize/1024; 

  printf("内存使用: %8lf \n",MemorySize);  //WorkingSetSize The current working set size, in bytes. 

  return MemorySize;
}  

void writeRecordtime(unsigned rTime)//将程序结果运行时间写入文件
{
  FILE *fpRecord=NULL;  

  char *s="your programm running time is:  ";
  char *c="ms  "; 

  if((fpRecord=fopen("record.txt","wt+"))==NULL)
  {
    printf("Cannot open file strike any key exit!");
    getchar();
    exit(1);
  }  

  fprintf( fpRecord, "%s", s);
  fprintf( fpRecord, "%d", rTime);
  fprintf( fpRecord, "%s", c); 

  fprintf( fpRecord, "\n");
  fprintf( fpRecord, "your programm use %fMB size of memory!!!", showMemoryInfo()); 

  fclose(fpRecord);
} 

int _tmain(int argc, _TCHAR* argv[])
{
  produceData(Data,MAX);
  printData(Data,MAX);
  getchar();
  return 0;
}
