NAME
   DecryptDataFinal,
   CSSM_DecryptDataFinal,
   CSP_DecryptDataFinal  - Finalize staged decryption process (CDSA)

 SYNOPSIS
   # include <cssm.h>

    API:
        CSSM_RETURN CSSMAPI CSSM_DecryptDataFinal
        (CSSM_CC_HANDLE CCHandle,
        CSSM_DATA_PTR RemData)
    SPI:
        CSSM_RETURN CSSMCSPI CSP_DecryptDataFinal
        (CSSM_CSP_HANDLE CSPHandle,
        CSSM_CC_HANDLE CCHandle,
        CSSM_DATA_PTR RemData)

 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.

   RemData (output)
           A pointer to the CSSM_DATA structure for the last decrypted
           block, if necessary.

 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 finalizes the staged decryption process by returning
   any remaining plain text not returned in the previous staged
   decryption call.  The plain text is returned in a single buffer.

 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,
   pre-allocated 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.
