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

 SYNOPSIS
   # include <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 (CDSA$INCSSM300_SHR.EXE)

 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.

   None specific to this call.
