I also try to make my program portable to the extent possible, but I have many
features that run only on Windows, placed in an #if defined(WIN32)...
For example, Falcon can't check stdin when not running on Windows (since it uses
PeekNamedPipe).
BTW, I think getting the vendorID of the processor will not cause any
portability issues. I do it using cpuid instruction:
int str1, str2, str3;
__asm {
mov eax, 00h
cpuid
mov str1, ebx
mov str2, edx
mov str3, ecx
}
sprintf(vendorId, "%c%c%c%c%c%c%c%c%c%c%c%c",
(str1), (str1 >> 8), (str1 >> 16), (str1 >> 24),
(str2), (str2 >> 8), (str2 >> 16), (str2 >> 24),
(str3), (str3 >> 8), (str3 >> 16), (str3 >> 24));
When running under Windows, I get the cpu_speed by:
RegOpenKeyEx(HKEY_LOCAL_MACHINE,
"Hardware\\Description\\System\\CentralProcessor\\0", 0,
KEY_QUERY_VALUE, &hKey);
RegQueryValueEx(hKey, "~MHz", NULL, &&mtype , (LPBYTE)&cpu_speed,
&size);
