NAME

       sg_get_user_stats,  sg_get_user_stats_r,  sg_free_user_stats  -  get the current logged in
       users

SYNOPSIS

       #include <statgrab.h>

       sg_user_stats *sg_get_user_stats (size_t *entries);

       sg_user_stats *sg_get_user_stats_r (size_t *entries);

       sg_error sg_free_user_stats (sg_user_stats *data);

DESCRIPTION

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

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