Given a Windows process handle, how can I determine, using C++ code, whether the process is 32 bit or 64 bit?
BOOL IsWow64(HANDLE process)
{
BOOL bIsWow64 = FALSE;
typedef BOOL(WINAPI *LPFN_ISWOW64PROCESS) (HANDLE, PBOOL);
LPFN_ISWOW64PROCESS fnIsWow64Process;
fnIsWow64Process = (LPFN_ISWOW64PROCESS)GetProcAddress(GetModuleHandle(TEXT("kernel32")), "IsWow64Process");
if (NULL != fnIsWow64Process)
{
if (!fnIsWow64Process(process, &bIsWow64))
{
//handle error
}
}
return bIsWow64;
}
bool IsX86Process(HANDLE process)
{
SYSTEM_INFO systemInfo = { 0 };
GetNativeSystemInfo(&systemInfo);
// x86 environment
if (systemInfo.wProcessorArchitecture == PROCESSOR_ARCHITECTURE_INTEL)
return true;
// Check if the process is an x86 process that is running on x64 environment.
// IsWow64 returns true if the process is an x86 process
return IsWow64(process);
}
