本文介绍了一种使用Windows API函数获取当前进程内存使用情况的方法。通过OpenProcess和GetProcessMemoryInfo函数组合，可以读取进程的各种内存计数器，如工作集大小、页错误计数等。

    PROCESS_MEMORY_COUNTERS ProMem = {0};
    ProMem.cb = sizeof(PROCESS_MEMORY_COUNTERS);

    HANDLE hProcess = OpenProcess(PROCESS_QUERY_INFORMATION | PROCESS_VM_READ,FALSE,GetCurrentProcessId());

    GetProcessMemoryInfo(hProcess,&ProMem,sizeof(ProMem));

    CloseHandle(hProcess);

    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;
