Don't know about the non-recoverable state, but you can refer the following links to delete the files programmatically:

Hi,

I am not sure that there is such API, but I think you have at least 2 options:

You can fill the file with zeros, save it and then remove it.
Use srm linux command.

Thanks for reply

i have followed the similar approach of what you have said

Before deleting the file ,i will overwrite the contents of the file with junk character and then i will delete the file so that even after recovery also original data is not there
