readline

Read line of ASCII string data from UDP socket

Since R2020b

Syntax

data = readline(u)

Description

data = readline(u) reads data from the specified UDP socket until the first occurrence of the terminator, and assigns the result to data as a string. If the function is unable to return any data within the period specified by the Timeout property of u, it returns data as a 0-by-0 double []. u must be a byte-type udpport object. This function waits until the terminator is read or a timeout occurs.
