Constructor

var procpid = require('proc-pid')({ stats : ['io', 'status'] });

.pid(pid, cb);

• pid is the process id of the process to look up in /proc
• cb is the callback
  • signature function (err, data)

The data object will contain an attribute for each of the stats requested in the constructor (which by default is io and status).
