 ** NAME
 **   extract_cus - Extracts creation time, unique_number and
 **                 split_job_counter from the message name
 **
 ** SYNOPSIS
 **   void extract_cus(char         *msg_name,
 **                    time_t       *creation_time,
 **                    unsigned int *split_job_counter,
 **                    unsigned int *unique_number)
 **
 ** DESCRIPTION
 **   This function extracts the creation time, unique_number and
 **   split_job_counter from the message name which has the
 **   following structure:
 **    <job_id>/<counter>/<creation_time>_<unique_no>_<split_job_counter>_
 **
 ** RETURN VALUES
 **   On success it returns the values for creation_time, split_job_counter,
 **   and unique_number. On error these values will be set to zero.
