[ILUG] ksh: What signal did trap trap?

[Éibhear]

Hi,

I am looking at a ksh script which has the following command:

trap "clean_up; report_error $ERR_CLOSE_DOWN; exit" 1 2 3 4 5 6 7 8 9 10 \
    11 12 13 14 15

where clean_up() and report_error() are ksh functions also defined in the
script.

Is there a way (e.g. an environment variable?) for me to determine what
signal was trapped so that I can report it in report_error()?

Thanks,

Éibhear
