types:illarg/4

illarg(+ErrorTerm, +Goal, +ArgNo, +Culprit) is det: Throw a SICStus standard error described by ErrorTerm. If possible, errors are thrown in the corresponding SWI-Prolog format using library(error). If a SICStus error has no SWI-Prolog counterpart, it is thrown in the same format that SICStus would use.
The Goal and ArgNo arguments are currently always ignored. Depending on the requested error type, Culprit and/or parts of ErrorTerm may also be ignored.
