/*
 * ew2rsam.c:  
 *
 *    Initial version by Lucky Vidmar Thu May  6 10:07:21 MDT 1999
 *
 *    This module reads trace messages from the InRing and computes
 *  rsam values over time periods defined in the configuration file.
 *  The rsam values are written out to the OutRing as a tracebuf
 *  message (TYPE_TRACEBUF), containing one value, with endtime 
 *  and starttime both equal to the time of the last sample in the
 *  rsam computation period; the sampling rate is the inverse of 
 *  the rsam averaging period.
 *    The channel name in the S-C-N of the newly produced message  
 *  is modified to reflect the Rsam nature of the message. The 
 *  original channel code is appended the string _Rx, where x is 
 *  the index of the rsam computation period (0 - 4). 
 *  If the newly generated channel name exceedes the maximum 
 *  length of the chan string, an error is reported and that message
 *  is NOT written out to the OutRing.
 *      
 *  The rsam computation algorithm was provided by Tom Murray
 *  (tlmurray@usgs.gov)
 *
