+getutmp, getutmpx \- copy utmp structure to utmpx, and vice versa
+.SH LIBRARY

+.SH DESCRIPTION
+The
+.BR getutmp ()
+function copies the fields of the
+.I utmpx
+structure pointed to by
+.I ux
+to the corresponding fields of the
+.I utmp
+structure pointed to by
+.IR u .
+The
+.BR getutmpx ()
+function performs the converse operation.
+.SH RETURN VALUE
+These functions do not return a value.

+glibc 2.1.1.
+Solaris, NetBSD.
+.SH NOTES
+These functions exist primarily for compatibility with other
+systems where the
+.I utmp
+and
+.I utmpx
+structures contain different fields,
+or the size of corresponding fields differs.
+.\" e.g., on Solaris, the utmpx structure is rather larger than utmp.
+On Linux, the two structures contain the same fields,
+and the fields have the same sizes.
