how to handle Ajax 401 (unauthorized access error) in Jquery datatables?

I am using a datatable as follows:

    $('#resources_table').dataTable({
    "processing": true,
    "serverSide": true,
    "columns": [
        { "data": "id" },
        { "data": "column1" },
        { "data": "column2" }
    ],
    "ajax": "/resource",
    "error": function(reason) {
        console.log("error encountered ! ");
        // process reason here to know the type of the error
        // and then take appropriate action
    }
});

Somehow I am not been able to catch error returned from the server. How to access reason and process error in serverside processing ajax based datatables?

PS: I am using the latest dataTable version: DataTables 1.10.1

Use:

ajax: {
  url: '/resource',
  error: function () {... }
}

There is no error option in DataTables top level options list: reference.

Thanks a lot Allan. I realized that 'ajax' options takes one of the 3 types of value: 'string', 'object', and 'function'. I used 'object' (similar to what you mentioned in your answer) to provide a custom 'error' callback.
