Gets the version of Windows

But I do not think I can use, tentatively note.
If the compiler can be compiled without problems and I think system Windows.
Tentatively, compile and confirm the operation was carried out in MinGW.

#include <windows.h> #include <stdio.h> int main(void) { unsigned int GV = GetVersion(); printf("GetVersion API(GV) = %08X\n\n", GV); printf("_winver = %08X\n", _winver); printf("_winmajor = %08X\n", _winmajor); printf("_winminor = %08X\n", _winminor); printf("_osver = %08X\n\n", _osver); printf("(( GV << 8 ) | (( GV >> 8 ) & 0XFF)) & 0XFFFF = %08X (= _winver)\n", (( GV << 8 ) | (( GV >> 8 ) & 0XFF)) & 0XFFFF ); printf("GV & 0XFF = %08X (= _winmajor)\n", GV & 0XFF ); printf("( GV >> 8 ) & 0XFF = %08X (= _winminor)\n", (( GV >> 8 ) & 0XFF)); printf("GV >> 16 = %08X (= _osver)\n\n\n", (GV >> 16) ); // Windows version(_winmajor, _winminor, _osver) printf("This system is ["); if ( _osver < 0X8000 ) { // NT Group (_osver LowWORD MSB = 0) switch (_winmajor) { case 3: case 4: printf ("Windows NT %u.%u Build %u", _winmajor, _winminor, _osver); break; case 5: switch (_winminor) { case 0: printf ("Windows 2000 Build %u", _osver); break; case 1: printf ("Windows XP Build %u", _osver); break; case 2: printf ("Windows Server 2003 family Build %u", _osver); break; default: printf ("NT Group Windows Build %u", _osver); } break; case 6: switch (_winminor) { case 0: printf ("Windows Vista or Windows Server 2008 Build %u", _osver); break; case 1: printf ("Windows 7 Build %u", _osver); break; default: printf ("NT Group Windows Build %u", _osver); } break; default: printf ("NTGroup Windows Build %u", _osver); } } else { switch (_winmajor ) { case 0: //Win32s Group case 1: case 2: case 3: printf ("Win32s Build %u", _osver & 0X7FFF); break; case 4: // 9X Group (_osver is invalid.) switch (_winminor) { case 0: printf ("Windows 95 Build ----"); break; case 10: printf ("Windows 98 Build ----"); break; case 90: printf ("Windows Me Build ----"); break; default: // To make sure printf ("Newer than Windows Me"); } break; default: // To make sure printf ("Newer than Windows Me"); } } printf("]"); return 0; }
