getutmp, getutmpx - copy utmp structure to utmpx, and vice versa
LIBRARY
Standard C library (libc, -lc)
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);

HISTORY
glibc 2.1.1. Solaris, 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.
