Re: How smart is Rosetta?

This is not the recommended way; for a better way, see http://developer.apple.com/documentation/MacOSX/Conceptual/universal_binary/universal_binary_exec_a/chapter_7_section_7.html

The sample code is a little more elaborate than necessary because it's designed around the idea of testing any PID to see if it's running in Rosetta, not just your own PID. In listing A-4, change sysctlbyname_with_pid to a plain sysctlbyname to simplify it. Or if you don't mind either way, just copy all the code and pass a PID of 0.

Anyway, Rosetta can be detected with the following bit of code:

bool CPSFMactel::IsRosetta() {
bool isRosetta = false;
    char model[32];
    size_t len = sizeof(model);
    int mib[2] = { CTL_HW, HW_MODEL };


    if (sysctl(mib, 2, &model, &len, NULL, 0) == 0) {
isRosetta = (len == 9 && strcmp(model, "PowerMac") == 0);
}


return isRosetta;
}
