signal SIGINTare both ways of sending an interrupt signal. Alternatively, if signal is zero, continue execution without giving a signal. This is useful when your program stopped on account of a signal and would ordinary see the signal when resumed with the
continuecommand; `signal 0' causes it to resume without a signal.
signaldoes not repeat when you press RET a second time after executing the command.
signal command is not the same as invoking the
kill utility from the shell. Sending a signal with
causes GDB to decide what to do with the signal depending on
the signal handling tables (see section Signals). The
passes the signal directly to your program.
