Otherwise, pString must point to valid application memory that is greater than or equal to *pSize bytes in length, and on return the pointed-to string will contain a space-separated list of kernel source attributes. Note: This API was originally intended to ship with a char *pString, however this typo was introduced. Thus the API has to stay this way for backwards compatible reasons. It can be corrected in v2.0. Suggestion is to create your own char *pString and then pass to this API with &pString.
