SecDecodeTransformCreate(_:_:)

Creates a decode transform object.

Declaration

func SecDecodeTransformCreate(_ DecodeType: CFTypeRef, _ error: UnsafeMutablePointer<Unmanaged<CFError>?>?) -> SecTransform?

Parameters

  • DecodeType:

    The type of digest to decode. You may pass NULL for this parameter, in which case an appropriate algorithm will be chosen for you. See Encoding Types for a list of valid values.

  • error:

    A pointer to a Cferror. This pointer will be set if an error occurred. This value may be NULL if you do not want an error returned.

Return Value

A pointer to a new transform or NULL on error. In Objective-C, call the CFRelease function to free this object’s memory when you are done with it.

Discussion

This function creates a transform which computes a decode.
