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

SYNOPSIS
  # include <cdsa/cssm.h>

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

LIBRARY
  Common Security Services Manager library (libcssm.so)

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 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 buffers.
  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 represent
  an error condition.

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