I would put retCode before caller position parameters(filename etc)

Supplying NULL retCode is a big usage mistake as you get wrong result code in this
case. Thus I would instead don't fail but give warning and continue. This way
correct error will be logged at least.
Eventually I think simpliest would be move PrlEvent_GetErrCode out of this function.
Also I would make it void as it is a logging function.
