	//
	//  Writes the given message to the log file
	//
	//  The log file is opened using fopen with a mode of "a+".  This opens the file for
	//  reading and appending.  The appending operation includes the removal of the EOF
	//  marker before new data is written to the file and the EOF marker is restored after
	//  writing is complete.  The file is created first if it doesn’t exist.
	//
	//  If an error occurs, ignore it.  Just means that the error message will not get
	//  written to the log file.
	//
