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

SYNOPSIS    [Toc]    [Back]

       # 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    [Toc]    [Back]

       Common Security Services Manager library (libcssm.so)

API PARAMETERS    [Toc]    [Back]

       The handle that describes  the  context  of  this  cryptographic
 operation used to link to the CSP-managed information.
  A pointer to a vector of CSSM_DATA structures  that
       contain  the  data  to  be  operated  on.   The  number of
       DataBufs to be verified.

SPI PARAMETERS    [Toc]    [Back]

       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    [Toc]    [Back]

       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    [Toc]    [Back]

       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    [Toc]    [Back]

       Errors  are described in the CDSA technical standard.  See
       CDSA_intro(3).

       None specific to this call.
