CFGetTypeID(_:)

Returns the unique identifier of an opaque type to which a Core Foundation object belongs.

Declaration

func CFGetTypeID(_ cf: CFTypeRef!) -> CFTypeID

Parameters

  • cf:

    The CFType object to examine.

Return Value

A value of type CFTypeID that identifies the opaque type of cf.

Discussion

This function returns a value that uniquely identifies the opaque type of any Core Foundation object. You can compare this value with the known CFTypeID identifier obtained with a “GetTypeID” function specific to a type, for example CFDateGetTypeID(). These values might change from release to release or platform to platform.
