[개발] c#,vc++ OS가 x86 인지 x64인지 알수 있는 방법

실행되는 프로그램의 OS의 32bit인지 64bit인지 알수 있는 방법.
IsWow64Process 함수에서 return 값이 false라면 64bit 프로세서이다.
흠.

[DllImport("kernel32.dll")] 
public static extern bool IsWow64Process(System.IntPtr hProcess, out bool lpSystemInfo); 
 
public static bool IsWow64Process1 
{ 
   get 
   { 
       bool retVal = false; 
       IsWow64Process(System.Diagnostics.Process.GetCurrentProcess().Handle, out retVal); 
       return retVal; 
   } 
}




Visual C++


#include <windows.h>
#include <stdio.h>

typedef BOOL (WINAPI *LPFN_ISWOW64PROCESS) (HANDLE, PBOOL);

LPFN_ISWOW64PROCESS fnIsWow64Process;

BOOL IsWow64()
{
    BOOL bIsWow64 = FALSE;

    //IsWow64Process is not available on all supported versions of Windows.
    //Use GetModuleHandle to get a handle to the DLL that contains the function
    //and GetProcAddress to get a pointer to the function if available.

    fnIsWow64Process = (LPFN_ISWOW64PROCESS) GetProcAddress(
        GetModuleHandle(TEXT("kernel32")),"IsWow64Process");

    if(NULL != fnIsWow64Process)
    {
        if (!fnIsWow64Process(GetCurrentProcess(),&bIsWow64))
        {
            //handle error
        }
    }
    return bIsWow64;
}

void main()
{
    if(IsWow64())
        printf("The process is running under WOW64.\n");
    else
        printf("The process is not running under WOW64.\n");
}
