Overview
A structure containing user-defined data and callbacks for CFHost objects.
Instance Attribute Summary (collapse)
-
- copyDescription
The callback used to create a descriptive string representation of the info pointer (or the data pointed to by the info pointer) for debugging purposes.
-
- release
The callback used to remove a retain previously added for the host on the info pointer.
-
- retain
The callback used to add a retain for the host on the info pointer for the life of the host, and may be used for temporary references the host needs to take.
-
- version
The version number of the structure type passed as a parameter to the host client function.

Instance Attribute Details
- (CFAllocatorCopyDescriptionCallBack) copyDescription
The callback used to create a descriptive string representation of the info pointer (or the data pointed to by the info pointer) for debugging purposes. This callback is called by the CFCopyDescription function.
- (CFAllocatorReleaseCallBack) release
The callback used to remove a retain previously added for the host on the info pointer.
- (CFAllocatorRetainCallBack) retain
The callback used to add a retain for the host on the info pointer for the life of the host, and may be used for temporary references the host needs to take. This callback returns the actual info pointer to store in the host, almost always just the pointer passed as the parameter.
- (CFIndex) version
The version number of the structure type passed as a parameter to the host client function. The only valid version number is 0.
