UTMP_UPDATE(8)						    BSD System Manager's Manual 					    UTMP_UPDATE(8)

NAME
utmp_update -- update utmpx database SYNOPSIS
utmp_update utmpx_entry DESCRIPTION
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 sufficient. EXIT STATUS
utmp_update returns 0 on success, and 1 if an error occurred. SEE ALSO
pututxline(3), utmpx(5) BSD

LOGIN(3)						   BSD Library Functions Manual 						  LOGIN(3)

NAME
login, logout, logwtmp -- login utility functions (DEPRECATED) SYNOPSIS
#include <util.h> void login(struct utmp *ut); int logout(const char *line); void logwtmp(const char *line, const char *name, const char *host); DESCRIPTION
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 in pututxline(3)). 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. RETURN VALUES
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. FILES
