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.
