VariableInformationStruct3 (STRUCT) ¶ TYPE VariableInformationStruct3 : STRUCT WARNING! If you pass this struct to the IecVarAccess or CmpIecVarAccess, it MUST be initialized with IIecVarAccess9.VarAccInitVarInfo() or IecVarAccInitVarInfo() before usage, and it MUST be cleaned up with IIecVarAccess9.VarAccExitVarInfo() or IecVarAccExitVarInfo(). Weird side effects including crashes and memory leaks will result if you do not adhere to this rule.
