find MASTER_LOG_POS in binary log (no replies)

Hi,
i have lvm backup of my mysql DB, and i like to use this backup for slave in a master slave configuration.
Is it correct to use the last finding of end_log_pos in the binlog for the setup of the slave with:
CHANGE MASTER TO MASTER_HOST=, MASTER_PORT=3306, MASTER_USER='', MASTER_PASSWORD=, MASTER_LOG_FILE=, MASTER_LOG_POS=;

Thank you
Helga
