CClosureProtocol
public protocol CClosureProtocol
A GCClosure
is a specialization of GClosure
for C function callbacks.
The CClosureProtocol
protocol exposes the methods and properties of an underlying GCClosure
instance.
The default implementation of these can be found in the protocol extension below.
For a concrete class that implements these methods and properties, see CClosure
.
Alternatively, use CClosureRef
as a lighweight, unowned
reference if you already have an instance you just want to use.
