pub unsafe extern "C-unwind" fn SecTransformCreateGroupTransform() -> CFRetained<SecGroupTransform>👎Deprecated: SecTransform is no longer supported
Available on crate feature
SecTransform only.Expand description
Create a SecGroupTransformRef that acts as a container for a set of connected transforms.
Returns: A reference to a SecGroupTransform.
A SecGroupTransformRef is a container for all of the transforms that are in a directed graph. A SecGroupTransformRef can be used with SecTransformExecute, SecTransformExecuteAsync and SecTransformCopyExternalRepresentation APIs. While the intention is that a SecGroupTransformRef willwork just like a S SecTransformRef that is currently not the case. Using a SecGroupTransformRef with the SecTransformConnectTransforms, SecTransformSetAttribute and SecTransformGetAttribute is undefined.
