How to use library function without creating instance/object

Here it is:

arduino-libraries/SD/blob/1.2.4/src/SD.cpp#L635


      
              //Serial.println("nothing");
              return File();
            }
          
            void File::rewindDirectory(void) {
              if (isDirectory()) {
                _file->rewind();
              }
            }
          
            SDClass SD;
          
          };

That makes it global so you can use it from the translation unit of the sketch.
