NAME
       updwtmp, logwtmp - append an entry to the wtmp file

SYNOPSIS
       #include <utmp.h>

       void updwtmp(const char *wtmp_file, const struct utmp *ut);
       void logwtmp(const char *line, const char *name, const char *host);

DESCRIPTION
       updwtmp() appends the utmp structure ut to the wtmp file.

       logwtmp()  constructs an utmp structure using line, name, host, current time and current process id.  Then it calls updwtmp() to append the
       structure to the utmp file.

AVAILABILITY
       Both functions are available under glibc2, but not under libc5.	However, logwtmp occurs in the old libbsd.

FILES
       /var/log/wtmp
	      database of past user logins
