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

SYNOPSIS
  # include <cdsa/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 (libcssm.so)

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_intro(3).
