This function allows your module to print messages to the RSPD's log file (such as when a configuration error has occurred). If the RSPD is running in debug mode, these messages will be printed to the console (otherwise they will be seen in the log file). The priority parameter can be one of three values: RSP_NOTE, RSP_WARN, and RSP_ERROR. These correspond to the three different error levels of RSPD log messages.
