winapi GetProcessMemoryInfo 无效参数问题

Question

我有这个问题，无法在这个测试代码上解决。

无效参数 候选人是：

？GetProcessMemoryInfo(？， _PROCESS_MEMORY_COUNTERS *， ？(

如何从进程内部确定 CPU 和内存消耗？

我尝试了GetProcessMemoryInfo(GetCurrentProcess((，&info，info.cb(;和 GetProcessMemoryInfo(GetCurrentProcess((，(*PROCESS_MEMORY_COUNTERS(&info，info.cb(;我使用 mingw64 版本明GW-W64-builds-4.2.0gcc 版本 4.9.2 具有： -std=c++1y -O0 -g3 -Wall -c -fmessage-length=0我尝试添加路径和包含，将 -lpaspi 添加到 eclipse 中的 gcc++ 构建参数中，但似乎没有任何帮助。有什么想法吗？

#include <windows.h>
#include <psapi.h>
LPVOID file_version;
HANDLE handle;
PROCESS_MEMORY_COUNTERS_EX info;
MEMORYSTATUSEX memoryInfo;
DWORDLONG totalVirtualMemory;
DWORDLONG virtualMemoryUsed;
SIZE_T virtualMemoryUsedByMe;
DWORDLONG totalPhysicalMemory;
DWORDLONG physicalMemoryUsed;
SIZE_T physicalMemoryUsedByMe;
void init(){
          bool error  =  GetFileVersionInfo("psapi.lib",0,GetFileVersionInfoSize("psapi.h",0),file_version);
          info.cb = sizeof(info);
            bool okay = GetProcessMemoryInfo(GetCurrentProcess(),(*PROCESS_MEMORY_COUNTERS)&info,info.cb);                      
           memoryInfo.dwLength = sizeof(MEMORYSTATUSEX);
          GlobalMemoryStatusEx(&memoryInfo);
          totalVirtualMemory = memoryInfo.ullTotalPageFile;//Total Virtual Memory:
          virtualMemoryUsed = memoryInfo.ullTotalPageFile - memoryInfo.ullAvailPageFile;//Virtual Memory currently used:
}
double GetCurrentValue(){
     HANDLE handle = GetCurrentProcess();
     info.cb = sizeof(info);
     GetProcessMemoryInfo(handle, (PROCESS_MEMORY_COUNTERS*)&info,info.cb);
     virtualMemoryUsedByMe = info.PrivateUsage; //Virtual Memory currently used by current process:
     totalPhysicalMemory = memoryInfo.ullTotalPhys;//Total Physical Memory (RAM):
     physicalMemoryUsed = memoryInfo.ullTotalPhys - memoryInfo.ullAvailPhys;//Physical Memory currently used:
     physicalMemoryUsedByMe = info.WorkingSetSize;//Physical Memory currently used by current process:
}

您正在传递一个未初始化的指针 (file_version(。它应该指向缓冲区。有关如何确定所需缓冲区的大小，请参阅 MSDN 文档。
