Re: [xSocket-develop] receiving data from server

[quan n. h. <hu...@gm...>]

in java socket, InputStream.read() return the next byte of data, or -1
if the end of the stream is reached. I used it to read data of each
stream.

InputStream in = sock.getInputStream();

byte[] temp = new byte[100];

// receive data
int length = in.read(temp);

& i think available() method here is similar.
