Hi All,
Thanks for the replies, however I'm noticing from the snippet below
FILE* commsPipe = NULL;
DEBUG_SHOW(CFStringCreateWithFormat(kCFAllocatorDefault, NULL,
CFSTR("Call external Tool (%s) withs Args(%s)."), cmd, pArguments) );
err = (WirelessError)AuthorizationExecuteWithPrivileges([auth
authorizationRef], &cmd[0], (unsigned long)kAuthorizationFlagDefaults,
argumentsChown, &commsPipe );
if ( err == noErr )
{
NSLog(@"Waiting for profile tool to finish.");
int child; wait(&child);
close(fileno(commsPipe));
NSLog(@"profile tool has finished.");
}
I notice from the NSLog's outputs that this code doesn't seem to be
waiting for that launched tool to finish, as I have also put some
NSLogs within the tool itself, as I do not see NSLog's timestamps
match up, as I would expect to see the timestamp of the above 'tool
has finished' to be the last in console log, however I see timestamps
after the 'wait' has returned.
Am I missing something here ?
Thanks
Mark.

Hi ALL,
I was wondering if anybody could tell me if it's correct to use
authorizationExecuteWithPrivileges and wait() calls together, so the
parent process wait's until that new child process finishes.
Googling seems to imply this from the examples I've seen.
However reading the documentation (within XCode) the
authorizationExecuteWithPrivileges, doesn't mention that the
privileged process is actually a child of the process which executed
this ? As while I can understand this, I thought maybe another
process actually launched the requested executable as root.
Thanks for any clarifications, as I would like to be sure this is
correct way to wait for process to finish when I call
authorizationExecuteWithPrivileges, and not this how it works today.
Thanks
Mark.
