Additional DPCL Programming Tasks

This section contains instructions for performing additional, more-advanced and/or less commonly performed DPCL programming tasks. These additional DPCL programming tasks are described in three chapters.

• Chapter 14, Handling signals and file descriptors through the DPCL system describes how an application can monitor UNIX signals and file descriptors through the DPCL system.
• Chapter 15, Searching for, and listing, functions in the target application describes how an analysis tool can list functions in the target application that match a supplied regular expression search pattern.
• Chapter 16, Overriding default system callbacks describes how an application can create callback routines to handle unexpected system events such as a DPCL daemon exiting or a target application process terminating. These callbacks then replace the default system callbacks which merely print out an error message.
• Chapter 17, Generating diagnostic logs describes how a program can, for troubleshooting and debugging purposes, create a log file that records the activities of the DPCL system.
