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  per‐
       forms 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
   Multithreading (see pthreads(7))
       The getutmp() and getutmpx() functions are thread-safe.

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.
