var execQ = new require('execq');

execQ.pend([socket, socket.write, argv]);
execQ.pend([socket, socket.write, argv]);
execQ.pend([socket, socket.write, argv]);
execQ.pend([socket, socket.write, [arg1, arg2...]]);

API

// init the max pending-queue lenght
var execQ = new require('exdecq')(maxlen);

maxlen default to 1000

// get pending queue's length
execQ.length // => x

// add a job to pending-queue
execQ.pend(operation);
  • operation {Array | Function}

ex:

// array
[object, function, [arg1, arg2, ..., argn]]

// execute a series of pended commands with a seqnum
execQ.goon(seqnum);

execute the commands from the seqnum

  • seqnum {Number} (option)
// clean the pending-queue
