socket_recv

Syntax

native socket_recv(_socket, _data[], _length);

Usage

Socket descriptor

Array to save the data

Length of the array

Description

Receives data.

Note

• The amount of bytes than you end up receiving can be less than the one you expected.

• This function will completely block the server until some data arrives
  to the given socket. Use this only if you are sure there is some data
  to be retrieved. You can do that by polling with socket_is_readable().

Return

Amount of bytes received
0 if the peer closed the connection
-1 on failure
