pprfproProfile (PPRFPROFILE) - in/out
The parameters of the PRFPROFILE data structure are set to the lengths of the respective file names, even if truncation occurs. If these fields are initialized to 0 by the application, then the parameters are not inspected, and the application can then determine the sizes of the buffers required to hold the names on a second call. Otherwise, the parameters must point to reserved areas of memory, and the parameters must indicate the sizes of those areas.
If the parameter is NULL, then there is no defined user or system profile, respectively.
