This is what I need, thanks mates. It shows up the username, TTY, node and date when the user failed to login to the system but I tought it would be easier to know this without having to translate it into ASCII code.
Or there is one?

ulog_login_pseudo
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 session 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 session 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 privileged process to perform the actual logging.
