#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);

LIBRARY

Standard C library (libc, -lc)

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.

HISTORY

glibc 2.1.1. Solaris, 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.
