TCP connections library

connect(ip, port, timeout)

Parameters:

• ip (string).

• port (number)

• timeout (number)

Return:

• number

Example Usage:

-- Connect to example.com on port 80
local connectionId = tcp.connect("example.com", 80, 5000)

sendBytes(connectionId, bytesTable)

Parameters:

• connectionId (number).

• bytesTable (table)

Return:

• boolean

Example Usage:

local connectionId = tcp.connect("example.com", 80, 5000)
if connectionId then
    local bytesTable = {}
    bytesTable[1] = 72  -- 'H'
    bytesTable[2] = 105 -- 'i'
    bytesTable[3] = 10  -- newline
    local success, sendError = tcp.sendBytes(connectionId, bytesTable)
    if success then
        print("✓ Bytes sent successfully")
    else
        print("✗ Send bytes failed: " .. sendError)
    end
end

receiveBytes(connectionId, timeout, size)

Parameters:

• connectionId (number).

• timeout (number)

• size (number)

Return:

• table

Example Usage:

local connectionId = tcp.connect("example.com", 80, 5000)
if connectionId then
    local bytesReceived, receiveError = tcp.receiveBytes(connectionId, 1000, 50)
    if bytesReceived then
        print("✓ Received " .. bytesReceived.length() .. " bytes")
        local data = encoding.bytesToString(bytesReceived, "UTF-8")
    else
        print("✗ Receive bytes failed: " .. receiveError)
    end
end

disconnect(connectionId)

Parameters:

• connectionId (number).

Return:

• boolean

Example Usage:

local connectionId = tcp.connect("example.com", 80, 5000)
if connectionId then
    local bytesReceived, receiveError = tcp.receiveBytes(connectionId, 1000, 50)
    if bytesReceived then
        print("✓ Received " .. bytesReceived.length() .. " bytes")
        local data = encoding.bytesToString(bytesReceived, "UTF-8")
    else
        print("✗ Receive bytes failed: " .. receiveError)
    end
    tcp.disconnect(connectionId)
end
