GETUTMP(3) Linux Programmer s Manual GETUTMP(3)

NAME getutmp, getutmpx - copy utmp structure to utmpx, and vice versa

SYNOPSIS #define _GNU_SOURCE #include <utmpx.h>

void getutmp(const struct utmpx *ux, struct utmp *u); void getutmpx(const struct utmp *u, struct utmpx *ux);

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.

RETURN VALUE These functions do not return a value.

VERSIONS These functions first appeared in glibc in version 2.1.1.

CONFORMING TO These functions are non-standard, but appear on a few other systems, such as Solaris and 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.
