Oracle® Developer Studio 12.5: Debugging a Program with dbx

Exit Print View

Updated: June 2016

Sending a Signal to a Program

The dbx cont command supports the -sig option, which enables you to resume execution of a program with the program behaving as if it had received the system signal signal.

For example, if a program has an interrupt handler for SIGINT (^C), you can type ^C to stop the application and return control to dbx. If you issue a cont command by itself to continue program execution, the interrupt handler never executes. To execute the interrupt handler, send the signal, SIGINT, to the program:

(dbx) cont -sig int

The step command, next command, and detach command also accept the -sig option.
