NAME
   VerifyDataUpdate,
   CSSM_VerifyDataUpdate,
   CSP_VerifyDataUpdate  - Continue the staged verification (CDSA)

 SYNOPSIS
   # include <cssm.h>

    API:
        CSSM_RETURN CSSMAPI CSSM_VerifyDataUpdate
        (CSSM_CC_HANDLE CCHandle,
        const CSSM_DATA *DataBufs,
        uint32 DataBufCount)
    SPI:
        CSSM_RETURN CSSMCSPI CSP_VerifyDataUpdate
        (CSSM_CSP_HANDLE CSPHandle,
        CSSM_CC_HANDLE CCHandle,
        const CSSM_DATA *DataBufs,
        uint32 DataBufCount)

 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.

   DataBufs (input)
           A pointer to a vector of CSSM_DATA structures that contain
           the data to be operated on.

   DataBufCount (input)
           The number of DataBufs to be verified.

 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 continues the staged verification process over all
   data contained in the set of input. Verification will be based on
   the signature presented as input when finalizing the staged
   verification process.

 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.
