* conversion specifications (%s, %d, %c, etc) causing the
* conversion and output of each successive argument after
* <code>message</code> As with printf, having a conversion
* character in <code>message</code> without an associated argument
* following it is an error.
*
* To ensure that no character in <code>message</code> is
* interpreted as requiring conversion, a safe way to call
* this method is:
* <code> reportToLog(severity, chanID, "%s", message); </code>
* @param severity severity level of report
* @param channelID area report relates to, from midp_constants_data.h
* @param message detail message to go with the report
* should not be NULL
