getutmp, getutmpx - copy utmp structure to utmpx, and vice versa
#define _GNU_SOURCE /* See feature_test_macros(7) */
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 per‐
forms the converse operation.
These functions do not return a value.
These functions first appeared in glibc in version 2.1.1.
Multithreading (see pthreads(7))
The getutmp() and getutmpx() functions are thread-safe.
These functions are nonstandard, but appear on a few other systems, such as Solaris and
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.
