Arduino File.findUntil()

Description

The File.findUntil() function reads data from the file until the target string of given length or terminator string is found, or it times out (see File.setTimeout()).

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

Syntax

file.findUntil(target, terminal)

Parameter Values

• file: an instance of a class that inherits from File.
• target: the string to search for. Allowed data types: char.
• terminal: the terminal string in the search. Allowed data types: char.

Return Values

The function returns true if target string is found, false if timed out.
