DigestDataUpdate

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

SYNOPSIS
  # include <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
  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.

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 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
  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.
