parseInt() returns the first valid (long) integer number from the current position. The function is terminated by the first character that is not a digit (except for the leading minus sign), or when it times out (see Stream.setTimeout()).
This function is part of the Stream class, and can be called by any class that inherits from it (Wire, Serial, etc). See the Stream class main page for more information.
