Special Event Breakpoints

The Breakpoints Window provides four special events for tracking your program. These events include:

On Exit Triggers when the process exits; either with the given exit code or with any exit code, if none is given; see Breaking On Exit for instructions.
On Signal Triggers when the process is about to receive the given signal; see Breaking On Signal for instructions.
On Return From Triggers just after the given function returns or, if no function is given, just after the current function returns; see Breaking On Return From for instructions.
On Exception Triggers when an exception of the given type is thrown or, if no type is given, when any exception is thrown; see Breaking On Exception for instructions.

dbx provides for other special events (for example, dlopen and system calls). To specify other events, choose Event CUSTOM and type the event specification in the Event text box. For more information on special events, see Events.
