NAME

6       getutmp, getutmpx - copy utmp structure to utmpx, and vice versa
7

SYNOPSIS

9       #define _GNU_SOURCE             /* See feature_test_macros(7) */
10       #include <utmpx.h>
11
12        void getutmp(const struct utmpx *ux, struct utmp *u);
13        void getutmpx(const struct utmp *u, struct utmpx *ux);
14

DESCRIPTION

16       The getutmp() function copies the fields of the utmpx structure pointed
17       to by ux to the corresponding fields of the utmp structure  pointed  to
18       by u.  The getutmpx() function performs the converse operation.
19

RETURN VALUE

21       These functions do not return a value.

CONFORMING TO

36       These functions are nonstandard, but appear on  a  few  other  systems,
37       such as Solaris and NetBSD.
38

NOTES

40       These  functions  exist  primarily for compatibility with other systems
41       where the utmp and utmpx structures contain different  fields,  or  the
42       size  of  corresponding  fields  differs.  On Linux, the two structures
43       contain the same fields, and the fields have the same sizes.
