Intermediate (kernel) interface
Intermediate interface is defined in MedHbWDefs.pas file. It contains some utility functions and declarations of interface functions located in medhbw.dll file. medhbw.dll file is used to provide Mediator functions services and as an intermediate layer when calling Harbour functions.
Usually, you do not need to directly use this intermediate interface. Just add MedHbWDefs.pas file to your Delphi project and don't worry about its contents.
