dictionary

typedef std::map<std::string, std::string> dx::wasapi::dictionary

matching dictionary: verb -> case-insensitive substring; id -> the KS filter device interface id, name -> PKEY_Device_FriendlyName, interface -> PKEY_DeviceInterface_FriendlyName, vendor -> PKEY_Device_Manufacturer. A driver's match is a vector of them: any dictionary whose entries all match takes the endpoint, an empty vector takes every endpoint
