GETUTMP(3)                                                              Linux Programmer's Manual                                                             GETUTMP(3)

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.

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.
