NAME
  CSSM_CSP_CreateMacContext - Create a message authentication code
  cryptographic context (CDSA)

SYNOPSIS
  # include <cdsa/cssm.h>

       CSSM_RETURN CSSMAPI CSSM_CSP_CreateMacContext
       (CSSM_CSP_HANDLE CSPHandle,
       CSSM_ALGORITHMS AlgorithmID,
       const CSSM_KEY *Key,
       CSSM_CC_HANDLE *NewContextHandle)

LIBRARY
  Common Security Services Manager library (libcssm.so)

PARAMETERS
  CSPHandle (input)
	  The handle that describes the add-in cryptographic service provider
	  module used to perform this function. If a NULL handle is
	  specified, CSSM returns error.

  AlgorithmID (input)
	  The algorithm identification number for the MAC algorithm.

  Key (input)
	  The key used to generate a message authentication code. Caller
	  passes a pointer to a CSSM_KEY structure containing the key.

  NewContextHandle (output)
	  Cryptographic context handle.

DESCRIPTION
  This function creates a message authentication code cryptographic context,
  given a handle of a CSP, algorithm identification number, and a key. The
  cryptographic context handle is returned. The cryptographic context handle
  can be used to call message authentication code functions.

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.
