Detailed Description

The basic interface of all interfaces.

Interfaces are identified by 16 byte Globally Unique Identifiers. The SDK provides a class called FUID for this purpose.

Member Function Documentation

◆ addRef()

virtual uint32 PLUGIN_API Steinberg::FUnknown::addRef ( )
pure virtual

Adds a reference and returns the new reference count.

Remarks:
The initial reference count after creating an object is 1.

Implemented in Steinberg::FObject.

◆ queryInterface()

virtual tresult PLUGIN_API Steinberg::FUnknown::queryInterface ( const TUID  _iid,
void **  obj 
)
pure virtual

Query for a pointer to the specified interface.

Returns kResultOk on success or kNoInterface if the object does not implement the interface. The object has to call addRef when returning an interface.

Parameters
_iid: (in) 16 Byte interface identifier (-> FUID)
obj: (out) On return, *obj points to the requested interface

Implemented in Steinberg::FObject.

◆ release()

virtual uint32 PLUGIN_API Steinberg::FUnknown::release ( )
pure virtual

Releases a reference and returns the new reference count.

If the reference count reaches zero, the object will be destroyed in memory.

Implemented in Steinberg::FObject.
