NAME
   SignDataFinal,
   CSSM_SignDataFinal,
   CSP_SignDataFinal - Complete the final stage of the sign data (CDSA)

 SYNOPSIS
   # include <cssm.h>

    API:
        CSSM_RETURN CSSMAPI CSSM_SignDataFinal
        (CSSM_CC_HANDLE CCHandle,
        CSSM_DATA_PTR Signature)
    SPI:
        CSSM_RETURN CSSMCSPI CSP_SignDataFinal
        (CSSM_CSP_HANDLE CSPHandle,
        CSSM_CC_HANDLE CCHandle,
        CSSM_DATA_PTR Signature)

 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.

   Signature (output)
           A pointer to the CSSM_DATA structure for the signature.

 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 completes the final stage of the sign data function.

 NOTES ON 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 ON SPI
   The output is returned to the caller as specifed 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.
