Need help with SdFat::ls function

Hi!
I need to send directory listing to a specified output stream (UART, Telnet...)
I'm trying to use function void SdFat::ls ( Print *  pr, uint8_t  flags = 0 ), but I don't understand what shall I pass to this function in Print *  pr variable.

Thank you!

but I don't understand what shall I pass to this function

You pass is a pointer to something that derives from the Print class. Look at the classes you want to use. Do they derive from Print? HardwareSerial derives from Stream which derives from Print, so you could pass the address of an instance of the HardwareSerial class (like Serial) to the function.

Can you give me the correct syntax example for Serial, please?
Pointers is not my strong side :\

Thank you! Every time I forgot about this symbol... and got compilation errors.
