/*
|
|
* TODO: This typedef is wrong.
|
|
*
|
|
* This is due to limitations of cffi.
|
|
* See https://bitbucket.org/cffi/cffi/issue/69
|
|
*
|
|
* For another possible work-around (not used here because it involves more
|
|
* complicated use of the cffi API which falls outside the general pattern used
|
|
* by this package), see
|
|
* http://paste.pound-python.org/show/iJcTUMkKeBeS6yXpZWUU/
|
|
*
|
|
* The work-around used here is to just be sure to declare a type that is at
|
|
* least as large as the real type. Maciej explains:
|
|
*
|
|
* <fijal> I think you want to declare your value too large (e.g. long)
|
|
* <fijal> that way you'll never pass garbage
