DESCRIPTION

20       The user statistics module delivers some information  about  logged  on
21       users.  Each logon is treated separately. Both statistic get functions,
22       sg_get_user_stats()  and  sg_get_user_stats_r(),  return  a  vector  of
23       sg_user_stats with entries elements.

35       The sg_user_stats vector received from  sg_get_user_stats_r()  must  be
36       freed  using  sg_free_user_stats() when not needed any more. The caller
37       is responsible for doing it.
