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.
ATTRIBUTES¶
For an explanation of the terms used in this section, see attributes(7).

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.
