SYNOPSIS

DESCRIPTION

       first  closes all open files, streams, directory streams, and message catalogue descriptors, if possible, then causes the signal to be sent
       to the calling process.	This may cause a core dump to be generated (see signal(2)).

       If the signal is caught, the handling function is executed.  If the handling function returns, the action for is then reset to and the sig-
       nal is sent again to the process to ensure that it terminates.

RETURN VALUE

       does not return.

ERRORS

       No errors are defined.

APPLICATION USAGE

       is not intended to be caught.

DIAGNOSTICS

       If is neither caught nor ignored, and the current directory is writable, a core dump is produced and the message is written by the shell.

SEE ALSO
