SignDataUpdate

NAME
  SignDataUpdate,
  CSSM_SignDataUpdate,
  CSP_SignDataUpdate  - Continue the staged signing process input
                        buffer data (CDSA)

SYNOPSIS
  # include <cssm.h>

   API:
       CSSM_RETURN CSSMAPI CSSM_SignDataUpdate
       (CSSM_CC_HANDLE CCHandle,
       const CSSM_DATA *DataBufs,
       uint32 DataBufCount)
   SPI:
       CSSM_RETURN CSSMCSPI CSP_SignDataUpdate
       (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 signed.

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 signing process over all data
  contained in the set of input buffers. Signing is performed using
  the private key specified in the context.

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.
