Glua-netcl uses Go net package. netcl.dial, conn:read, conn:readline, conn:write, conn:set_timeouts and conn:Close ara available.

local net = require("netcl")

local conn, err = net.dial("tcp", "127.0.0.1:8899", 1000)
if err then error(err) end

local count, err = conn:write("test_a")
if err then error(err) end

local resp, err = conn:read(256)
if err then error(err) end

netcl.dial(network string, address string, timeout number) -> net_client, string

Arguments:

• network string - name of the network ("tcp", "udp", "ip", "ip4", "ip6")
• adress string - address of the remote host
• timeout number - timeout in milliseconds

Returns:

• net_client - user defined type for connection
• string - error description if any, nil if no errors

conn:read(count number) -> string, string

Arguments:

• count number - maximum number of bytes to read

Returns:

• string - readed data
• string - error message or nil

conn:write(data string) -> number, string

Arguments:

• data string - data to write

Returns:

• number - number of bytes readed
• string - error message or nil

conn:set_timeouts(read_timeout number, write_timeout number)

Arguments:

• read_timeout number - timeout for read in milliseconds
• write_timeout number - timeout for write in milliseconds

conn:close()
