高分求助！！！（在VC开发平台下如何得到内存及CPU占用率等数据）

[jasonloo]

各位大侠：
如何在VC＋＋开发平台下得到Windows系统CPU的占用率和内存的使用情况，
就像“任务管理”下动态呈现的数据一样，有相应的API函数吗？谢谢！

可以
GetSystemInfo取得与底层硬件平台有关的信息
可以看看这里的一些api

硬件与系统函数里面

关于内存的绝大多数信息可以通过以下函数获得：

BOOL GetProcessMemoryInfo(
HANDLE Process, // handle to process
PPROCESS_MEMORY_COUNTERS ppsmemCounters, // buffer
DWORD cb // size of buffer
);

The GetProcessMemoryInfo function retrieves information about the memory usage of the specified process in the PROCESS_MEMORY_COUNTERS structure.

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;
typedef PROCESS_MEMORY_COUNTERS *PPROCESS_MEMORY_COUNTERS;

获得cpu时间:
BOOL GetProcessTimes(
HANDLE hProcess, // handle to process
LPFILETIME lpCreationTime, // process creation time
LPFILETIME lpExitTime, // process exit time
LPFILETIME lpKernelTime, // process kernel-mode time
LPFILETIME lpUserTime // process user-mode time
);

关于io信息：
BOOL GetProcessIoCounters(
HANDLE hProcess, // handle to process
PIO_COUNTERS lpIoCounters // I/O accouting information
);

谢谢，我先试一下！
