LSGetApplicationForURL() failed

Hi,

I am developing an application tool that requires a function which will give me users default browser name.

I have code as below

FSRef appRef;

CFURLRef inUrl;

OSStatus status;

CFStringRef urlString;

CFURLRef appUrlRef;

CFStringRef defBrowserName;

cfURLStr = CFStringCreateWithCString(kCFAllocatorDefault, "http://www.quickheal.com", kCFStringEncodingUTF8);

if (NULL == urlString) exit(-1);

inUrl = CFURLCreateWithString(NULL, urlString, NULL);

status = LSGetApplicationForURL(inUrl, kLSRolesEditor, &appRef, &appUrlRef);

if (noErr != status) {
CFRelease(inUrl); CFRelease(urlString); exit(-1); }

defBrowserName = CFURLCopyLastPathComponent(inUrl);

NSLog(@"Here is Default Browser Name %@", (NSString *)defBrowserName);

This code works well when i am normal user. But when i ran same code as super user, it give me error

that

LSGetApplicationForURL() failed. Error:(-10814)

Why this happened?

I am waiting for some quick replies which i had not got last time.

Thanks in advance,

You searched wrongly.

It took me about 5 seconds to find this: https://developer.apple.com/library/mac/#documentation/Carbon/Reference/LaunchSe rvicesReference/Reference/reference.html

The launch services database is maintained at a user level. Either super user does not have a LS DB or there is no entry in it for an app that browses. The bigger question is: Why on earth are you trying this from super user?
