Further information
This function returns the next dependency of a model: model dependencies are the packages it includes and the modules it requires. The second parameter is used to store the current location in the table of dependencies; if this parameter is NULL, the first dependency of the table is returned. This function returns NULL if it is called with the reference to the last dependency defined by the given model. Otherwise, the returned value can be used as the input parameter ref to get the following dependency and so on. Note that this function allocates memory when it is called for the first time and releases the allocated data when all items have been returned ( i.e. the function returns NULL).
