  8. Destroy a stream.
  9. This module is meant to ensure a stream gets destroyed, handling different APIs
  10. and Node.js bugs.
  11. ## API
  12. ```js
  13. var destroy = require('destroy')
  14. ```
  15. ### destroy(stream)
  16. Destroy the given stream. In most cases, this is identical to a simple
  17. `stream.destroy()` call. The rules are as follows for a given stream:
  18. 1. If the `stream` is an instance of `ReadStream`, then call `stream.destroy()`
  19. and add a listener to the `open` event to call `stream.close()` if it is
  20. fired. This is for a Node.js bug that will leak a file descriptor if
  21. `.destroy()` is called before `open`.
  22. 2. If the `stream` is not an instance of `Stream`, then nothing happens.
  23. 3. If the `stream` has a `.destroy()` method, then call it.
  24. The function returns the `stream` passed in as the argument.
  25. ## Example
  26. ```js
  27. var destroy = require('destroy')
  28. var fs = require('fs')
  29. var stream = fs.createReadStream('package.json')
  30. // ... and later
  31. destroy(stream)
  32. ```
