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.
