NAME
getutmp, getutmpx - copy utmp structure to utmpx, and vice versa
SYNOPSIS
#define _GNU_SOURCE /* See feature_test_macros(7) */
#include <utmpx.h>
void getutmp(const struct utmpx *ux, struct utmp *u);
void getutmpx(const struct utmp *u, struct utmpx *ux);
DESCRIPTION
The
getutmp()
function copies the fields of the
utmpx
structure pointed to by
ux
to the corresponding fields of the
utmp
structure pointed to by
u.
The
getutmpx()
function performs the converse operation.
RETURN VALUE
These functions do not return a value.
VERSIONS
These functions first appeared in glibc in version 2.1.1.
ATTRIBUTES
For an explanation of the terms used in this section, see
attributes(7).

CONFORMING TO
These functions are nonstandard, but appear on a few other systems,
such as Solaris and NetBSD.
NOTES
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.
