Q: I am trying to write an application that, when run on a PCI Mac, queries the
Name Registry database for the processor type and speed. I've been unable to
find anything in Inside Macintosh: Designing PCI Cards and Drivers on this
topic. Where can I find this information?
A: The Name Registry does not contain this information, but you can obtain it from
the Gestalt Manager, just as you did on 68K Macs. This is discussed in
Inside Macintosh: Operating System Utilities.
If you have a utility that already does this on a 68K Mac, it should also work
on a PCI Mac. The code snippet below shows how to get the processor type:
// This snippet calls the Gestalt Manager to read the machine type.
#include <stdio.h>#include <GestaltEqu.h>
// prototypes
void main(void);
void main(void)
{
OSErr iErr = 0;
OSType selector = 'mach';
long response = 0;
printf("DTS Absolutely Free (Gratis) Snippet\n\n");
iErr = Gestalt(selector,&response);
if(!iErr)
printf("The informational selector 'mach' is %ld \n", response);
else
printf("Sorry, an error has occurred\n");
}
