SYNOPSIS
  # include <cssm.h>

       CSSM_RETURN CSSMAPI CSSM_UnwrapKeyP
       (CSSM_CC_HANDLE CCHandle,
       const CSSM_KEY *PublicKey,
       const CSSM_WRAP_KEY *WrappedKey,
       uint32 KeyUsage,
       uint32 KeyAttr,
       const CSSM_DATA *KeyLabel,
       const CSSM_RESOURCE_CONTROL_CONTEXT *CredAndAclEntry,

LIBRARY
  Common Security Services Manager library (CDSA$INCSSM300_SHR.EXE)

PARAMETERS
  Privilege (input)
          The privilege to be applied during the cryptographic
          operation.

  See CSSM_UnwrapKey.

DESCRIPTION
  This function is similar to CSSM_UnwrapKey(). It also accepts a USEE
  tag as a privilege request parameter. CSSM checks that either its
  own privilege set or the Application's privilege set (if the
  Application is signed) includes the tag. If the tag is found and the
  service provider privilege set indicates that it is supported, the
  tag is forwarded to the service provider.

NOTES
  The KeyData field of the CSSM_KEY structure is allocated by the CSP.
  The application is required to free this memory using the
  CSSM_FreeKey() function or with the memory functions registered for
  the CSPHandle.

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.

       CSSMERR_CSP_KEY_LABEL_ALREADY_EXISTS
       CSSMERR_CSP_PUBLIC_KEY_INCONSISTENT
       CSSMERR_CSP_PRIVATE_KEY_ALREADY_EXIST
