“Datatypes for C method implementation functions” shows the datatypes displayed in EAServer Manager, the datatypes used by C components, and the argument modes. The left column contains the datatype name as it displays in EAServer Manager. The second and third columns contain the names of the corresponding C datatypes for input, inout, and output parameters.
If the EAServer Manager method definition returns a value other than ResultSet or ResultSets, an additional output parameter is added to the front of the implementation function’s parameter list. This additional parameter receives the “logical return code” for the method invocation, as described in “Logical method return values”.
