Function SecTransformCreateFromExternalRepresentation 

pub unsafe extern "C-unwind" fn SecTransformCreateFromExternalRepresentation(
    dictionary: &CFDictionary,
    error: *mut *mut CFError,
) -> Option<CFRetained<SecTransform>>

👎Deprecated: SecTransform is no longer supported

Available on crate feature SecTransform only.

Creates a transform instance from a CFDictionary of parameters.

Parameter dictionary: The dictionary of parameters.

Parameter error: An optional pointer to a CFErrorRef. This value is set if an error occurred. If not NULL the caller is responsible for releasing the CFErrorRef.

Returns: A pointer to a SecTransformRef object. You must release the object with CFRelease when you are done with it. A NULL will be returned if an error occurred during initialization, and if the error parameter is non-null, it contains the specific error data.

Safety

• dictionary generics must be of the correct type.
• error must be a valid pointer or null.
