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

function	returns	data owner
sg_get_user_stats	sg_user_stats *	libstatgrab (thread local)
sg_get_user_stats_r	sg_user_stats *	caller

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.

typedef struct {
        char *login_name;
        char *record_id;
        size_t record_id_size;
        char *device;
        char *hostname;
        pid_t pid;
        time_t login_time;
        time_t systime;
} sg_user_stats;
