*)Nonecorresponds 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 ofs, according toclauses. An exceptioneis caught by the first clause(spec,(name, decl, _, _)),bodysuch that the type ofeis compatible with(spec,decl).nameis then associated to a copy ofe, andbodyis executed. If thesingle_nameisNone, all exceptions are caught by the corresponding clause.The corresponding
TryCatchnode inCil_types.stmtkindhas a refined notion of catching that allows a clause to match for more than one type using appropriate conversions (see alsoCil_types.catch_binder).This node is not generated by the C parser, but can be used by external front-ends.
