	The bufptr parameter points to an array of SESSION_INFO_2 structures.
10	The bufptr parameter points to an array of SESSION_INFO_10 structures.
502	The bufptr parameter points to an array of SESSION_INFO_502 structures.

bufptr

Pointer to the buffer in which the data set with the level parameter is stored.
