    Parameters:
    
    tmpDir - A temporary directory to use to copy the native library to when loading from the classpath. If null, or the empty string, we rely on Java's File.createTempFile(String, String) function to provide a temporary location. The temporary file will be registered for deletion on exit.

    java.io.IOException - if a filesystem operation fails.
