NAME    [Toc]    [Back]

       DigestDataUpdate,  CSSM_DigestDataUpdate  -  Continue  the
       staged process of digesting (CDSA)

SYNOPSIS    [Toc]    [Back]

       # include <cdsa/cssm.h>

       API:     CSSM_RETURN     CSSMAPI     CSSM_DigestDataUpdate
       (CSSM_CC_HANDLE   CCHandle,   const  CSSM_DATA  *DataBufs,
       uint32 DataBufCount) SPI: CSSM_RETURN CSSMCSPI CSP_DigestDataUpdate
   (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.

SPI PARAMETERS    [Toc]    [Back]

       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    [Toc]    [Back]

       This function continues the staged  process  of  digesting
       all  data  contained  in  the  set  of  input buffers. The
       resulting digest value will be returned  as  part  of  the
       staged digesting 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.
