Variable length of function argument list in Erlang -

-

Is it possible to define tasks with the variable length logic?

I know that I can only write: 

  function () - & gt; Ceremony ([]) Function (x) when not is_list (x) - & gt; Ceremony ([X]); Function (x) - & gt; Do_something_with_arguments (x).

But I want to avoid this technique.

The only way to do this is to give all the arguments in one list:

< P> function (ListOfParameters)

And then you said ListOfParameters . In this way, you may be able to accept any "Parameter" declaration of your function, just add more conditions to declare ... but I'm not sure what you were hoping for. Are you thinking on the lines of a C code parameter list? In the positive case, read the next paragraph.

You must remember that the Eralong is based on pattern matching. The arguments given in the function "declaration" provide a function as a matching pattern if applicable.

To completely use the power of ERROR, leave your "procedural programming" mentality .

And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
