[1] Windows Programing - 查詢記憶體使用量

範例:

.h

#ifndef EXTRAAPI_H
#define EXTRAAPI_H

class extraAPI
{
public:
 extraAPI();
 ~extraAPI();

 static void memoryinfo();
};

#endif // EXTRAAPI_H

.cpp

#include "windows.h"
#include "stdio.h"
#include "psapi.h"

// 需加入這兩個lib
#pragma comment(lib, "strmiids.lib")
#pragma comment(lib, "psapi.lib")

void extraAPI::memoryinfo()
{
 PROCESS_MEMORY_COUNTERS pmc;
 GetProcessMemoryInfo( GetCurrentProcess(), &pmc, sizeof(pmc)); //get memory usage

 MEMORYSTATUSEX statex;
 statex.dwLength = sizeof (statex);
 GlobalMemoryStatusEx (&statex);
 (statex.ullTotalPhys-statex.ullAvailPhys)/1024;  // 全部已使用記憶體 3213064 (Kb)
 pmc.WorkingSetSize/1024;       // 此程式WorkingSet記憶體: 18832 (Kb)
}
