UTMP_UPDATE(8) BSD System Manager's Manual UTMP_UPDATE(8)NAME
utmp_update -- update utmpx database
utmp_update is a helper program to allow a user to update his own utmpx(5) entry. utmp_update does some consistency checks on the
strvis(3)-encoded utmpx_entry and then updates the utmpx(5) database of currently logged in users.
utmp_update should not be called directly, but will normally only be called by pututxline(3) if the privileges of the calling user are not
utmp_update returns 0 on success, and 1 if an error occurred.

LOGIN(3) BSD Library Functions Manual LOGIN(3)NAME
login, logout, logwtmp -- login utility functions (DEPRECATED)
login(struct utmp *ut);
logout(const char *line);
logwtmp(const char *line, const char *name, const char *host);
The login(), logout(), and logwtmp() functions are DEPRECATED; use pututxline(3) instead.
These functions operate on the database of current users in /var/run/utmpx and the system log file. Superuser permission is required.
The login() function updates the /var/run/utmpx files with user information contained in ut (after converting to a struct utmpx, as described
The logout() function removes the entry from /var/run/utmpx corresponding to the device line.
The logwtmp() function adds an entry to the system log file. Since login() will add the appropriate entry during a login, logwtmp() is usu-
ally used for logouts.
logout() returns non-zero if it was able to find and delete an entry for line, and zero if there is no entry for line in /var/run/utmpx.
However, there is no error indication due to lack of permissions.

I'm writing a short script to check if a continuous port is running on a server.

I installed NetBSD 6.1.2 amd64 and can't find the apm utility. Is it not in the base system?
Is it necessary to recompile the default amd64 kernel to use apm?
Or is there a new method for power management and suspend/resume? (2 Replies)
