Hi,I want to log something in a file at /private/var/log, using
NSFileHandle.With the app launched as root, everything runs ok using
[NSFileHandle fileHandleForWritingToURL:url error:&err]. I get a valid handle
and can write what I want to.
With the app launched as non-root user, I create an Authorization using
AuthorizationCreate(), with following flags:m_AuthFlags =
kAuthorizationFlagDefaults | kAuthorizationFlagInteractionAllowed |
kAuthorizationFlagExtendRights;
and further use it using AuthorizationCopyRights(m_AuthRef, &m_AuthRights,
NULL, m_AuthFlags, NULL)), which returns errAuthorizationSuccess.However, the
call of [NSFileHandle fileHandleForWritingToURL:url error:&err] throws the
Cocoa Error 13 (Permission Denied).It seems that although having set
kAuthorizationFlagExtendRights, I am still not allowed to open and write this
file located at /private/var/log.Am I doing something wrong here, to cause such
permission denial?Thx.
