 ** NAME
 **   get_log_type_data - reads the log data types from given pointer
 **
 ** SYNOPSIS
 **   void get_log_type_data(char *ptr)
 **
 ** DESCRIPTION
 **   Reads the log data types fron the given pointer ptr. Currently
 **   it reads the following values:
 **         LOG_DATE_LENGTH, MAX_HOSTNAME_LENGTH
 **
 ** RETURN VALUES
 **   If it finds any good values it returns them in the global
 **   variables.
