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

SYNOPSIS    [Toc]    [Back]

       # include <cdsa/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    [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 signed.

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 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    [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.
