Section (3) getutmp
getutmp, getutmpx — copy utmp structure to utmpx, and vice versa
#define _GNU_SOURCE /* See feature_test_macros(7) */ #include <utmpx.h>
||const struct utmpx *ux,|
|struct utmp *u
||const struct utmp *u,|
|struct utmpx *ux
copies the fields of the utmpx structure pointed to by
ux to the corresponding fields
of the utmp structure pointed
getutmpx() function performs
the converse operation.
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.
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.
