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.

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.
