NAME
  DigestDataClone, CSSM_DigestDataClone, CSP_DigestDataClone - Clone a staged
  message digest (CDSA)

SYNOPSIS
  # include <cdsa/cssm.h>

       API:
       CSSM_RETURN CSSMAPI CSSM_DigestDataClone
       (CSSM_CC_HANDLE CCHandle,
       CSSM_CC_HANDLE *ClonednewCCHandle)
       SPI:
       CSSM_RETURN CSSMCSPI CSP_DigestDataClone
       (CSSM_CSP_HANDLE CSPHandle,
       CSSM_CC_HANDLE CCHandle,
       CSSM_CC_HANDLE ClonednewCCHandle)

LIBRARY
  Common Security Services Manager library (libcssm.so)

API PARAMETERS
  CCHandle (input)
	  The handle that describes the context of a staged message digest
	  operation.

  ClonednewCCHandle (output)
	  The cloned digest context handle. The handle will be set to
	  CSSM_INVALID_HANDLE if the function fails.

SPI PARAMETERS
  CSPHandle (input)
	  The handle that describes the add-in cryptographic service provider
	  module used to perform calls to CSSM for the memory functions
	  managed by CSSM.

DESCRIPTION
  This function clones a given staged message digest context with its
  cryptographic attributes and intermediate result.

NOTES
  When a digest context is cloned, a new context is created with data
  associated with the parent context. Changes made to the parent context
  after calling this function will not be reflected in the cloned context.
  The cloned context could be used with the CSSM_DigestDataUpdate() and
  CSSM_DigestDataFinal() functions.

RETURN VALUE
  A CSSM_RETURN value indicating success or specifying a particular error
  condition. The value CSSM_OK indicates success. All other values represent
  an error condition.

ERRORS
  Errors are described in the CDSA technical standard.	See CDSA_intro(3).
