Deleted lines 8-9:

Note that the data is not physically written to the SD card until the file is closed (with a call to the close() function) or explicitly synced (with the flush() function). If the file was opened in mode FILE_APPEND, the data will be appended to the end of the file, regardless of the current cursor position set by seek().

Parameters

data (optional): the data to print (char, byte, int, long, or string)
