HISTORY glibc 2.1.1. Solaris, NetBSD. NOTES These functions exist primarily for compatibility with other systems where the utmp and utmpx structures contain different fields, or the size of corresponding fields differs. On Linux, the two structures contain the same fields, and the fields have the same sizes. SEE ALSO utmpdump(1), getutent(3), utmp(5) Linux man-pages 6.9.1 2024-05-02 getutmp(3)
