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.

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.
