可可应用程序的大小为/ dev / disk0s1
||
如何在Cocoa应用程序中通过分区的设备名称（例如/ dev / disk0s1）获取分区的大小（以字节为单位）？也许我应该以某种方式使用磁盘仲裁框架？

DASessionRef session = DASessionCreate(NULL); if (session) { DADiskRef disk = DADiskCreateFromBSDName(NULL, session, \"/dev/disk0s1\"); if (disk) { CFDictionaryRef diskDescription = DADiskCopyDescription(disk); NSDictionary *diskData = (NSDictionary *)diskDescription; NSString *diskSizeKey = (NSString *)kDADiskDescriptionMediaSizeKey; unsigned long size = [[diskData objectForKey:diskSizeKey] unsignedLongValue]; NSLog(@\"size in bytes = %lu\", size); CFRelease(diskDescription); CFRelease(disk); } else NSLog(@\"Error while getting DA disk for /dev/disk0s1\"); CFRelease(session); } else NSLog(@\"Error while creating DA session\");
