What does "new" do when called on an erlang module do?

I've seen module_name:new used in Erlang code, but there is no reference to a "ne开发者_运维问答w" function in the module_name module. What does "new" do?

It is for "parametrized module": see here and there for more details.

        'new'/2 =
    fun (_cor1,_cor0) ->
     apply 'instance'/2
         (_cor1, _cor0)
'instance'/2 =
    fun (_cor1,_cor0) ->
     {'p',_cor1,_cor0}  %%GOTCHA!!!!!
