如何从Mac硬盘获取序列号？ [英] How to get serial number from Mac hard disks?

问题描述

有没有任何简单的方法来获取Mac中使用任何API的所有硬盘的序列号？

Is there any easy way to get the serial number of all the hard disks in a Mac using any API's?

基本上寻找硬盘的唯一标识符，我应该知道，硬盘已被我的应用程序使用（推荐）。

Basically looking for a unique identifier for hard disk, with which I should make out that the Hard disk has been used(referred) by my application or not. Please let me know if there is any other solution.

注意：我需要10.4及以上版本的此解决方案。

Note: I need this solution in 10.4 and above.

推荐答案

我不知道AppleUSBEHCI是否是正确的寻找，但你可以使用IOKit框架检索这种数据：

I'm not sure if "AppleUSBEHCI" is the proper thing to look for but you can retrieve this sort of data using the IOKit framework:

#include <IOKit/IOKitLib.h>
#include <Cocoa/Cocoa.h>

kern_return_t   kr;
io_iterator_t   io_objects;
io_service_t    io_service;

kr = IOServiceGetMatchingServices(kIOMasterPortDefault,
            IOServiceNameMatching("AppleUSBEHCI"), &io_objects);

if(kr != KERN_SUCCESS)
    exit(1);

while((io_service= IOIteratorNext(io_objects)))
{
    kr = IORegistryEntryCreateCFProperties(io_service, &service_properties, kCFAllocatorDefault, kNilOptions);
    if(kr == KERN_SUCCESS)
    {
        NSDictionary * m = (NSDictionary *)service_properties;
        NSLog(@"%@", m);
        CFRelease(service_properties);
    }

    io_iterator_t   iter;
    //handle kr error
    kr = IORegistryEntryGetChildIterator(io_service, kIOServicePlane, &iter);

    io_registry_entry_t     child;
    while( (child = IOIteratorNext( iter )))
    {
        kr = IORegistryEntryCreateCFProperties(child, &child_props,  kCFAllocatorDefault, kNilOptions );
        NSLog(@"Child props: %@", child_props);
        //release child_props
    }

    IOObjectRelease(io_service);
}

IOObjectRelease(io_objects);
