catch

Tells Prism to catch the specified Solaris signal.

SYNTAX

catch [number | signal_name] [pset set_name | set_definition]

DESCRIPTION

Prism can catch Solaris signals before they are sent to the program. Use the catch command to tell Prism to catch the signal you specify. When Prism receives the signal, execution stops, and Prism prints a message. A subsequent cont from a naturally occurring signal that is caught causes the signal to be propagated to signal handlers in the program (if any); if there is no handler for the signal, the program terminates--in other words, the program proceeds as if Prism were not present.

By default, Prism catches all signals except SIGHUP, SIGEMT, SIGKILL, SIGALRM, SIGTSTP, SIGCONT, SIGCHLD, and SIGWINCH; you can use the ignore command to add other signals to this list.

Specify the signal by number or by name. Signal names are case-insensitive, and the SIG prefix is optional.

Issue catch without an argument to list the signals that Prism is to catch.

When issued in MP Prism, this command can take a pset qualifier. If used with a qualifier, it applies to the pset you specify. If used without a qualifier, it applies to the current pset. See " Using Pset Qualifiers" for more information on pset qualifiers.
