PARAMETERS
  CCHandle (input)
          The handle to the existing context.

          The number of CSSM_CONTEXT_ATTRIBUTE structures to allocate.

  ContextAttributes (input)
          Pointer to data that describes the attributes to be associated
          with this context.

DESCRIPTION
  This function updates one or more context attribute values stored as
  part of an existing context specified by CCHandle. The basic context
  structure is not modified by this function. Only the context attributes
  are updated.

  The NumberOfAttributes parameter specifies the number of attributes to
  update. The new attribute values are specified in ContextAttributes.
  If an attribute provided in ContextAttributes is already present in the
  existing context, the existing value is replaced by the new value. If
  an attribute provided in ContextAttributes is not present in the
  existing context, then the new attribute is added. Attribute values are
  never deleted from the existing context.

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.
