74 These functions are nonstandard, but appear on a few other systems,
75 such as Solaris and NetBSD.
77 These functions exist primarily for compatibility with other
82 structures contain different fields,
83 or the size of corresponding fields differs.
84 .\" e.g., on Solaris, the utmpx structure is rather larger than utmp.
85 On Linux, the two structures contain the same fields,
86 and the fields have the same sizes.
