Using Signal Processing

continues to run. Use the showproc command to see whether the process

is still running. Then use the suspend command to stop the process.

Continuing After Catching a Signal

The cont command allows you to continue execution after catching a signal.

You can also use the cont command to specify a different signal to send to

your program than the one thatdbx caught. Using the same syntax, you can

also send a signal to your program when you continue, even if your program

did not stop because of a caught signal.

Use the following forms of the cont command when handling signals. In

each case, if you do not provide a signal, but your program stopped because

dbx caught a signal intended for your program, then dbx sends that signal to

your program when you continue execution:

cont [signal] Continues execution with the current line and sends the

speciﬁed signal to your program.

cont [signal] {at | to} line

Sets a temporary breakpoint at the speciﬁed source line,

then resumes execution with the current line and sends the

speciﬁed signal to your program.

cont [signal] in procedure

Sets a temporary breakpoint to stop execution upon

entering the speciﬁed procedure, then resumes execution

with the current line and sends the speciﬁed signal to your

program.

For example, if your program stopped because dbx caught a SIGINT signal,

dbx will automatically send that signal to your program, if you enter:

(dbx) cont

Suppose you have a procedure called alarm_handler to handle an alarm

signal sent to your program. If you want to test this procedure by single-

stepping through it, you can execute the following command:

(dbx) cont SIGALRM in alarm_handler

This sets a temporary breakpoint to stop your program upon entering

alarm_handler, continues execution of your program, and sends a
