int PL_get_signum_ex(term_t t, int *sig)

Extract a signal specification from a Prolog term and store as an integer signal number in sig. The specification is an integer, a lowercase signal name without SIG or the full signal name. These refer to the same: 9, kill and SIGKILL. Leaves a typed, domain or instantiation error if the conversion fails.
