Стандарты (Conforming to)
These functions are nonstandard, but appear on a few other
systems, such as Solaris and NetBSD.
Примечание (Note)
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.
