Typedefs
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

Functions
std::string	dx::wasapi::devnode (const std::string &topology)
	device instance path of a KS filter: its device interface id without the {2}.\?\ prefix and the #{KSCATEGORY}<reference string> tail - shared by every endpoint of one device
uint32_t	dx::wasapi::number (::IMMDevice *endpoint, const ::PROPERTYKEY &key)
	a numeric property of an endpoint (VT_UI4 - the form factor, the physical speakers): zero where the endpoint carries none
std::string	dx::wasapi::property (::IMMDevice *endpoint, const ::PROPERTYKEY &key)
std::string	dx::wasapi::topology (::IMMDevice *endpoint)
	device interface id of the KS filter behind the endpoint's connector: {2}.\\?\<enumerator>#<hardware id>#<instance>#{KSCATEGORY}\<reference string>
std::string	dx::wasapi::utf8 (const wchar_t *wide)
std::wstring	dx::wasapi::wide (const std::string &utf8)
