Interacting With Other Modules

When designing your module you may well find that there is some functionality that you require in the module that is already available to you in other modules. Utility modules have been designed specifically to provide additional often-used functionality for modules in a standard way, and sometimes the functionality of an entire module might be used as part of your module.

Functionality can be obtained either from the display part of the module or the API itself, depending on the specific requirements in the new module. Interaction with other modules is carried out in different ways depending on the type of module being written and the level of specific control the module requires over the function being called.
