|Oracle Solaris Studio 12.3: Debugging a Program With dbx Oracle Solaris Studio 12.3 Information Library|
When an event occurs, dbx allows you to stop a process, execute arbitrary commands, or print information. The simplest example of an event is a breakpoint. Examples of other events are faults, signals, system calls, calls to dlopen(), and data changes.
