Thanks for your hints,i tried and understood:

def test
  caller_locations(1,2)
end
def chk
  test
end
test #=> ["/home/kirti/ruby/test.rb:7:in `<main>'"]
chk #=> ["/home/kirti/ruby/test.rb:5:in `chk'", 
"/home/kirti/ruby/test.rb:8:in `<main>'"]

def test
  caller_locations(1,1)
end
def chk
  test
end
p chk #=> ["/home/kirti/ruby/test.rb:14:in `chk'"]

The only thing I do not understand is  - ***The optional start parameter 
determines the number of initial stack entries to omit from the top of 
the stack.**  - I used in my example `optional start parameter` as `1`. 
But not seen any effect of its. I am sure i don't understand about the 
usefulness of that parameter. please help.
