read

read :: (stream: *Tls_Stream, buffer: [] u8) -> (s64, Io.Io_Error)

Waits for data and reads what is there, up to buffer.count bytes. 0 is the end: the peer sent close_notify. A connection that ends without it is an error (.CONNECTION_RESET, and last_error says .TRUNCATED): the data may have been cut off.

Parameters

stream: *Tls_Stream

the stream to read from.

buffer: [] u8

where the bytes go. Empty returns 0 at once.

Returns

s64

Io.Io_Error

read_greeting :: (stream: *Tls_Stream) -> string {
    buffer: [64] u8;
    count, error := read(stream, buffer);
    if error != .NONE || count == 0 return "";
    return copy_string(string.{ count, buffer.data });
