Since we don't allow the "printf" arguments, to prevent someone from adding arguments thinking they'll be used, it's probably best to call these:
errlogMessage
and
errlogMessageNoConsole

We could provide just one routine "errlogMessage" with a second optional argument with the console/noconsole flag though that doesn't match the real errlogMessage prototype and could cause confusion.  (Though maybe we could also change the errlogMessage function to add a second argument?).  Maybe providing both is best even though it adds to the proliferation of registered functions.

Thanks,
Stephanie
