NAME
       GenerateMacUpdate, CSSM_GenerateMacUpdate, CSP_GenerateMacUpdate - Con‐
       tinue the staged process of computing  a	 message  authentication  code
       (CDSA)

SYNOPSIS
       # include <cdsa/cssm.h>

       API:  CSSM_RETURN CSSMAPI CSSM_GenerateMacUpdate (CSSM_CC_HANDLE CCHan‐
       dle, const CSSM_DATA *DataBufs, uint32 DataBufCount)  SPI:  CSSM_RETURN
       CSSMCSPI CSP_GenerateMacUpdate (CSSM_CSP_HANDLE CSPHandle, CSSM_CC_HAN‐
       DLE CCHandle, const CSSM_DATA *DataBufs, uint32 DataBufCount)

LIBRARY
       Common Security Services Manager library (libcssm.so)

API PARAMETERS
       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 num‐
       ber of DataBufs.

SPI PARAMETERS
       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  process	of computing a message
       authentication code over all data contained in the set  of  input  buf‐
       fers. The authentication code will be returned as a result of the final
       code generation step.

RETURN VALUE
       A CSSM_RETURN value indicating success or specifying a particular error
       condition. The value CSSM_OK indicates success. All other values repre‐
       sent an error condition.

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

       None specific to this call.
