Question

api判断是32位系统还是64位

Answer 1

typedef void (WINAPI *PGNSI)(LPSYSTEM_INFO); pGNSI = (PGNSI)GetProcAddress(GetModuleHandle(_T("kernel32.dll")), "GetNativeSystemInfo"); if (NULL != pGNSI) { pGNSI(&si); } else { GetSystemInfo(&si); }

通过判断 si.wProcessorArchitecture

如果是 PROCESSOR_ARCHITECTURE_AMD64 // 64 bits如果是 PROCESSOR_ARCHITECTURE_INTEL // 32 bits
