 NAME
   DigestDataFinal,
   CSSM_DigestDataFinal,
   CSP_DigestDataFinal  - Finalize the staged message digest (CDSA)

 SYNOPSIS
   # include <cssm.h>

    API:
        CSSM_RETURN CSSMAPI CSSM_DigestDataFinal
        (CSSM_CC_HANDLE CCHandle,
        CSSM_DATA_PTR Digest)
    SPI:
        CSSM_RETURN CSSMCSPI CSP_DigestDataFinal
        (CSSM_CSP_HANDLE CSPHandle,
        CSSM_CC_HANDLE CCHandle,
        CSSM_DATA_PTR Digest)

 LIBRARY
   Common Security Services Manager library (CDSA$INCSSM300_SHR.EXE)

 API PARAMETERS
   CCHandle (input)
           The handle that describes the context of this cryptographic
           operation used to link to the CSP-managed information.

   Digest (output)
           A pointer to the CSSM_DATA structure for the message digest.

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

 DESCRIPTION
   This function finalizes the staged message digest function.

 NOTES FOR API
   The output is returned to the caller either by filling the caller-
   specified buffer or by using the application's declared memory
   allocation functions to allocate buffer space. To specify a
   specific, preallocated output buffer, the caller must provide an
   array of one or more CSSM_DATA structures, each containing a Length
   field value greater than zero and a non-NULL data pointer field
   value. To specify automatic output buffer allocation by the CSP, the
   caller must provide an array of one or more CSSM_DATA structures,
   each containing a Length field value equal to zero and a NULL data
   pointer field value. The application is always responsible for
   deallocating the memory when it is no longer needed.

 NOTES FOR SPI
   The output is returned to the caller as specified in Buffer Management
   for Cryptographic Services.

 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.
