First useful piece of Mac Code!

Hey everybody...

Today in response to some of my own tinkering and the forum at http://discussions.apple.com/thread.jspa?messageID=6978579#6978579 I have created my first useful program in Objective-C and MacOS. The utility is a command line application that will mount and return the path to the Leopard time machine volume.

The utility can be downloaded here http://rapidshare.de/files/39024900/GetTimeMachinePath.html

The souce code is as follows:

#import <Foundation/Foundation.h>

#import <AppKit/AppKit.h>

#import <CoreData/CoreData.h>

FSRef* getTimeMachineVolume()

{

NSData *timeMachinePList = [NSData dataWithContentsOfFile:@"/Library/Preferences/com.apple.TimeMachine.plist"];

NSString *errorText;

NSDictionary *timeMachineProperties = [NSPropertyListSerialization propertyListFromData:timeMachinePList mutabilityOption:NSPropertyListImmutable format:NULL errorDescription:&errorText];

NSData *backupAlias = [timeMachineProperties objectForKey:@"BackupAlias"];

AliasHandle aliasHandle = (AliasHandle)NewHandle([backupAlias length]);

[backupAlias getBytes: *aliasHandle];

FSRef *volumePath = malloc(sizeof(FSRef));

Boolean wasChanged;

OSErr resultOfResolve = FSResolveAlias(NULL, aliasHandle, volumePath, &wasChanged);

if (resultOfResolve != noErr)

return nil;

DisposeHandle((Handle)aliasHandle);

return volumePath;

}

int main (int argc, const char * argv[]) {

NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];

// insert code here...

char *timeMachinePOSIXPathString = malloc(1024 * sizeof(char));

FSRef *timeMachineFSRef = getTimeMachineVolume();

FSRefMakePath(timeMachineFSRef, (UInt8*)timeMachinePOSIXPathString, 1024 * sizeof(char));

free(timeMachineFSRef);

printf(timeMachinePOSIXPathString);

[pool drain];

return 0;

}
