I am looking for some function calls(cocoa/carbon or bsd) to obtain the free disk space on a machine.

How about this:

OSErr FSGetVInfo( FSVolumeRefNum volume, HFSUniStr255 volumeName, / can be NULL / UInt64 *freeBytes, / can be NULL / UInt64 *totalBytes) / can be NULL */ { OSErr result; FSVolumeInfo info;

/* ask for the volume’s sizes only if needed */ result = FSGetVolumeInfo(volume, 0, NULL, (((NULL != freeBytes) || (NULL != totalBytes)) ? kFSVolInfoSizes : kFSVolInfoNone), &info, volumeName, NULL); require_noerr(result, FSGetVolumeInfo);

if ( NULL != freeBytes ) { *freeBytes = info.freeBytes; } if ( NULL != totalBytes ) { *totalBytes = info.totalBytes; }

FSGetVolumeInfo:

return ( result ); }

OK, so I cribbed it from MoreFilesX found at http://developer.apple.com/samplecode/MoreFilesX/listing2.html

Use the search function: DiskSpace

I use this modified from the DiskSpace

• (unsigned)freeDiskSpace:(NSString*)path { unsigned long long sizeValue; NSNumber *keyValue; NSString *fullPath = [path stringByStandardizingPath]; if (fullPath) { NSFileManager *fm = [NSFileManager defaultManager]; if (fm) { NSDictionary *fileSystemAttributes = [fm fileSystemAttributesAtPath:fullPath]; if (fileSystemAttributes && [fileSystemAttributes count]) { keyValue = [fileSystemAttributes objectForKey:NSFileSystemFreeSize]; if (keyValue) { sizeValue = [keyValue unsignedLongLongValue]; NSLog(@”The current free space on the volume containing "%@" is %qu”, fullPath, sizeValue); return sizeValue; } } } } return 0; }
