Hello,
I have a cocoa program which run as a single task for a single user. It
have no problem when running Jaguar and below since only one user can
use it at one time. However on Panther with the feature "fast user
switching", the program can be run by many users. The program was
design to run one single process because it takes a lot computer time
and it does not share data files (one global directory). It will be a
havoc, if 2 or more of the programs running at a same time.
Is it possible to detect another instance of the program running by
another user ?
Thanks in Advance.
Peter.
