NAME
       VerifyMac, CSSM_VerifyMac, CSP_VerifyMac - Verify the message authenti‐
       cation code (CDSA)

SYNOPSIS
       # include <cdsa/cssm.h>

       API: CSSM_RETURN CSSMAPI CSSM_VerifyMac (CSSM_CC_HANDLE CCHandle, const
       CSSM_DATA  *DataBufs,  uint32  DataBufCount, const CSSM_DATA *Mac) SPI:
       CSSM_RETURN   CSSMCSPI	CSP_VerifyMac	(CSSM_CSP_HANDLE    CSPHandle,
       CSSM_CC_HANDLE  CCHandle,  const CSSM_CONTEXT *Context, const CSSM_DATA
       *DataBufs, uint32 DataBufCount, const CSSM_DATA *Mac)

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.  A pointer to the CSSM_DATA structure containing the
       MAC to verify.

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.   Pointer  to	CSSM_CONTEXT  structure	 that  describes   the
       attributes with this context.

DESCRIPTION
       This  function  verifies	 the message authentication code over all data
       contained in the set of input buffers based on the input signature.

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).	   CSSMERR_CSP_INPUT_LENGTH_ERROR     CSSMERR_CSP_VER‐
       IFY_FAILED CSSMERR_CSP_INVALID_SIGNATURE
