Since we're using * UUIDs as interface identifiers (IIDs) now, no only generic PDM interface will * be added to this file. Component specific interface should be defined in the * header file of that component. * * Interfaces consists of a method table (typedef'ed struct) and an interface * ID. The typename of the method table should have an 'I' in it, be all * capitals and according to the rules, no underscores. The interface ID is a * \#define constructed by appending '_IID' to the typename. The IID value is a * UUID string on the form "a2299c0d-b709-4551-aa5a-73f59ffbed74". If you stick * to these rules, you can make use of the PDMIBASE_QUERY_INTERFACE and * PDMIBASE_RETURN_INTERFACE when querying interface and implementing * PDMIBASE::pfnQueryInterface respectively. * * In most interface descriptions the orientation of the interface is given as * 'down' or 'up'. This refers to a model with the device on the top and the * drivers stacked below it. Sometimes there is mention of 'main' or 'external' * which normally means the same, i.e. the Main or VBoxBFE API.
