SystemStats::is64Bit would be handy. It’s useful if you’re doing things like running 32-bit code on a 64-bit OS.
Here’s a Windows version:
[code]#ifdef _WIN64
bool SystemStats::is64Bit()
{
return true;
}
#else
typedef BOOL (WINAPI *LPFN_ISWOW64PROCESS) (HANDLE, PBOOL);
bool SystemStats::is64Bit()
{
LPFN_ISWOW64PROCESS
fnIsWow64Process = (LPFN_ISWOW64PROCESS)GetProcAddress(GetModuleHandle(“kernel32”),“IsWow64Process”);
BOOL bIsWow64 = FALSE;
if (NULL != fnIsWow64Process)
{
fnIsWow64Process(GetCurrentProcess(),&bIsWow64);
}
return FALSE != bIsWow64; // convert from BOOL to bool
}
#endif
