[Bug-readline] Help to write custom completion function

[velusamy Krishnan]

Dear All,
      I am new to the readline library, I just used the example program which is used to complete the list of the commands. Now I just complete arguments for the commands. The arguments for the commands differ based on the given commands. So, I have to get the given command, and after pressing the tab I should list the possible argument for that command. 
      I know this is basic, but could not find the document to understand that.  Kindly anyone please help me..


Regards,
Velusamy.
