Illustrator Scripting :: Returning The Status Of Linked File

I´m having this problem:
 
I created and array to receive linked filed (let´s say var pItem = app.activeDocument.placedItems;)
 
After it, I used a loop to know the File each link is associated. So:
 
for (var g=0; g<pItem.length;g++){
   var src = pItem.file >>>>>>>>>>>>>>>>>>> The problem is here. If we have a missing link in the document, the script will stop with the message.
      ... continue procedure     
};
  
Of Course, I could try using an "try" statement...but..Just to know: Is there any way to evaluate the status of a placedItem (to know if it´s missing or not)?? In the user manual I did not find any property that checks for this. We have properties to check for bounds, matrix, notes, tags, if it´s locked, visible...but not for checking the consistency of a placedItem, right?
