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

NAME         top

       getutmp, getutmpx - copy utmp structure to utmpx, and vice versa

SYNOPSIS         top

       #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         top

       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         top

       These functions do not return a value.

VERSIONS         top

       These functions first appeared in glibc in version 2.1.1.

CONFORMING TO         top

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

NOTES         top

       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.
