sg_get_user_stats
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.
API Shortcut
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.
RETURN VALUES
The structure returned is of type sg_user_stats.
