GETUTMP(3) Linux Programmer's Manual GETUTMP(3)
getutmp, getutmpx - copy utmp structure to utmpx, and vice versa
#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);
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.
These functions do not return a value.
These functions first appeared in glibc in version 2.1.1.
For an explanation of the terms used in this section, see
attributes(7).

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