   This function is call during controller init phase as describe in onload-daemon-sample.json
   It receives two argument 1st one is the source (here on load) second one is the arguments
   as expose in config file.

   In this sample we create an event that take the name of args["zzzz"], the resulting handle
   is save into _Global_Context for further use.

   Note: init functions are not call from a client and thus do not receive query

function _Sample_Controller_Init(source, control)

    printf ("[-- Sample_Controller_Init --] source=%d control=%s", source, Dump_Table(control))

    -- if no argument return now
    if (control==nil or control["zzzz"]==nil) then
        printf ("[-- Sample_Controller_Init --]  no event name given")
        return
    end

    -- set a count to make more visible each call
    _Global_Context["counter"]=0

    -- just for fun create an event
    _Global_Context["event"]=AFB:evtmake(control["zzzz"])
