getutmp(3)                 Library Functions Manual                 getutmp(3)

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

LIBRARY
       Standard C library (libc, -lc)

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.

HISTORY
       glibc 2.1.1.  Solaris, 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.
