Arduino File.seek()

Description

The File.seek() function seeks to a new position in the file, which must be between 0 and the size of the file (inclusive).

The File.seek() function inherits from the Stream utility class.

Syntax

file.seek(pos)

Parameters

• file: an instance of the File class that is returned by SD.open()
• pos: the position to which to seek (unsigned long)

Returns

• True for success, false for failure (boolean)
