ULOG_LOGIN(3)		 BSD Library Functions Manual		 ULOG_LOGIN(3)

NAME
     ulog_login, ulog_login_pseudo, ulog_logout, ulog_logout_pseudo -- manage
     user login	records

LIBRARY
     User Login	Record Library (libulog, -lulog)

SYNOPSIS
     #include <ulog.h>

     void
     ulog_login(const char *line, const	char *user, const char *host);

     void
     ulog_login_pseudo(int fd, const char *host);

     void
     ulog_logout(const char *line);

     void
     ulog_logout_pseudo(int fd);

DESCRIPTION
     The ulog_login() and ulog_login_pseudo() functions	register a login ses-
     sion on a TTY.  The ulog_login() function adds an entry for TTY line and
     username user.  The ulog_login_pseudo() function uses file	descriptor to
     a pseudo-terminal master device fd	to determine the TTY name, while using
     the username belonging to the real	user ID	of the calling process.	 The
     optional host argument denotes a remote hostname, in case the login ses-
     sion is provided by a network service.

     The ulog_logout() and ulog_logout_pseudo()	functions mark the previously
     registered	login session as being terminated.

     Because the line and user arguments of ulog_login() and ulog_logout()
     cannot be trusted,	these functions	require	administrative privileges.
     The ulog_login_pseudo() and ulog_logout_pseudo() functions	spawn a	privi-
     leged process to perform the actual logging.
