Select New leaks to search for memory leaks in your application as it is running.
This command invokes the Purify API function purify_new_leaks() in your application by sending a signal. The signal is hidden from your application, but may interrupt slow system calls (read, write, select, sleep), causing them not to set errno to EINTR. If your application is not designed to handle interrupted system calls, this may result in unexpected behavior.
Notes:
Purify's memory leaked summary message reports leaks when the application has exited.
