【内存】的获取个人小结

标签：内存

本文为个人使用后的一些总结，逐步完善中...

1、获得全局内存

对应函数：void GlobalMemoryStatus(LPMEMORYSTATUS lpBuffer); 【总内存2G以内使用】

API:

typedef struct _MEMORYSTATUS
{  
	DWORD dwLength;			//本结构的长度;
	DWORD dwMemoryLoad;     //已用内存的百分比;
	SIZE_T dwTotalPhys;		//物理内存总量;
	SIZE_T dwAvailPhys;		//可用物理内存;
	SIZE_T dwTotalPageFile; //交换文件总的大小;
	SIZE_T dwAvailPageFile; //交换文件中空闲部分大小; 
	SIZE_T dwTotalVirtual;  //用户可用的地址空间;
	SIZE_T dwAvailVirtual;  //当前空闲的地址空间;
} MEMORYSTATUS, *LPMEMORYSTATUS;

使用实例：

void CGetMemory_1Dlg::OnBnClickedButton1()
{
	MEMORYSTATUS lpBuffer;
	lpBuffer.dwLength = sizeof(MEMORYSTATUS);
	GlobalMemoryStatus(&lpBuffer);
}

API:

typedef struct _MEMORYSTATUSEX {
    DWORD dwLength;
    DWORD dwMemoryLoad;
    DWORDLONG ullTotalPhys;
    DWORDLONG ullAvailPhys;
    DWORDLONG ullTotalPageFile;
    DWORDLONG ullAvailPageFile;
    DWORDLONG ullTotalVirtual;
    DWORDLONG ullAvailVirtual;
    DWORDLONG ullAvailExtendedVirtual;
} MEMORYSTATUSEX, *LPMEMORYSTATUSEX;

void CGetMemory_1Dlg::OnBnClickedButton1()
{
	MEMORYSTATUSEX lpBuffer;
	lpBuffer.dwLength = sizeof(MEMORYSTATUSEX);
	GlobalMemoryStatusEx(&lpBuffer);
}

call:

BOOL GetProcessMemoryInfo(
  HANDLE Process,
  PPROCESS_MEMORY_COUNTERS ppsmemCounters,
  DWORD cb
);

API:

typedef struct _PROCESS_MEMORY_COUNTERS 
{  
	DWORD cb;  
	DWORD PageFaultCount;  
	SIZE_T PeakWorkingSetSize;  
	SIZE_T WorkingSetSize;  
	SIZE_T QuotaPeakPagedPoolUsage;  
	SIZE_T QuotaPagedPoolUsage;  
	SIZE_T QuotaPeakNonPagedPoolUsage;  
	SIZE_T QuotaNonPagedPoolUsage;  
	SIZE_T PagefileUsage;  
	SIZE_T PeakPagefileUsage;
} PROCESS_MEMORY_COUNTERS, *PPROCESS_MEMORY_COUNTERS;
