在Mac OS X上获取CPU说明 [英] Obtaining CPU descriptions on Mac OS X

问题描述

我想以编程方式获取Mac OS X上的CPU描述，如下所示:

I'd like to programmatically get the CPU descriptions on Mac OS X, which look something like this:

Intel(R) Core(TM)2 CPU 6700 @ 2.66GHz
Intel(R) Xeon(R) CPU X5550 @ 2.67GHz

在Linux上可以执行grep "^model name" /proc/cpuinfo，而在Windows上可以查看注册表中HKLM\Hardware\Description\System\CentralProcessor\0中的ProcessorNameString值，但是如何在OS X上获取该信息?

On Linux you can do grep "^model name" /proc/cpuinfo and on Windows you can look at the ProcessorNameString value in HKLM\Hardware\Description\System\CentralProcessor\0 in the registry, but how do you get that information on OS X?

推荐答案

您可以将machdep.cpu.brand_string传递给sysctl来检索您要查找的字符串.

You can pass machdep.cpu.brand_string to sysctl to retrieve the string you're looking for.

[ben@imac ~]$ sysctl machdep.cpu.brand_string
machdep.cpu.brand_string: Intel(R) Core(TM) i5-2400S CPU @ 2.50GHz

相同的信息通过sysctl(3)功能公开.

The same information is exposed through the sysctl(3) functions.

[ben@imac ~]$ cat sys.c
#include <sys/types.h>
#include <sys/sysctl.h>
#include <stdio.h>

int main(int argc, char *argv[]) {
    char buf[100];
    size_t buflen = 100;
    sysctlbyname("machdep.cpu.brand_string", &buf, &buflen, NULL, 0);

    printf("%s\n", buf);
}

[ben@imac ~]$ ./sys
Intel(R) Core(TM) i5-2400S CPU @ 2.50GHz
