(*
throws the corresponding expression. None corresponds to re-throwing the exception currently being caught (thus is only meaningful in a catch clause). This node is not generated by the C parser, but can be used by external front-ends.
*)
| TRY_CATCH of statement * (single_name option * statement) list * cabsloc
(*
TRY_CATCH(s,clauses,loc) catches exceptions thrown by execution of s, according to clauses. An exception e is caught by the first clause (spec,(name, decl, _, _)),body such that the type of e is compatible with (spec,decl). name is then associated to a copy of e, and body is executed. If the single_name is None, all exceptions are caught by the corresponding clause.
The corresponding TryCatch node in Cil_types.stmtkind has a refined notion of catching that allows a clause to match for more than one type using appropriate conversions (see also Cil_types.catch_binder).
This node is not generated by the C parser, but can be used by external front-ends.
