getutmp, getutmpx — copy utmp structure to utmpx, and vice versa
#define _GNU_SOURCE #include <utmpx.h>
void getutmp( |
const struct utmpx *ux, |
struct utmp *u); |
void getutmpx( |
const struct utmp *u, |
struct utmpx *ux); |
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.
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.
