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.
