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.
This is an indirect answer since I don't know the real one :-/ I use the BetterAuthorizationSample (BAS) library, and my Cocoa process is *not* the parent of the privileged process. I don't think this can happen since I think it would break the UNIX model -- a process escalating its privilege (other than executing a SUID, SGID file). Rather, a launchd process already running as root executes my program with the requested privileges and communication from my Cocoa program to the privileged process is over a socket.
Using the BAS library, the function call does block until the requested remote procedure call finishes (and you get the results from the call in the response dictionary). But the privileged process can actually live a while longer waiting for subsequent calls. If none come after a certain amount of time, then it dies.
