getutmp, getutmpx - copy utmp structure to utmpx, and vice versa
#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);
These functions do not return a value.
These functions first appeared in glibc in version 2.1.1.
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
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.
