Question

我有这个问题，无法解决这个测试代码。

无效参数候选人是：

？ GetProcessMemoryInfo（？，_PROCESS_MEMORY_COUNTERS *，？）

How to determine CPU and memory consumption from inside a process?

我尝试了GetProcessMemoryInfo（GetCurrentProcess（），＆amp; info，info.cb）; 和GetProcessMemoryInfo（GetCurrentProcess（），（* PROCESS_MEMORY_COUNTERS）＆amp; info，info.cb）; 我使用mingw64版本MinGW-W64-builds-4.2.0 gcc版本4.9.2： - std = c ++ 1y -O0 -g3 -Wall -c -fmessage-length = 0 我尝试添加路径和包含，在eclipse中添加了-lpaspi到gcc ++构建参数，但似乎没有任何帮助。任何想法？

#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:
}

您正在传递未初始化的指针（file_version）。它应该指向一个缓冲区。有关如何确定所需缓冲区大小的信息，请参阅MSDN文档。
