### 173. Inconsistent types for `basic_filebuf::setbuf()`

Discussion:

In 29.10.2 [filebuf] the function `setbuf()` gets an object of type `streamsize` as second argument. However, in 29.10.2.5 [filebuf.virtuals] paragraph 9 the second argument is of type `int`.

As far as I can see this is not really a contradiction because everything is consistent if `streamsize` is typedef to be `int`. However, this is almost certainly not what was intended. The same thing happened to `basic_istream::ignore()`, as described in issue 172.

Proposed resolution:

In 29.10.2.5 [filebuf.virtuals] paragraph 9, change all uses of `int` in the description of `setbuf()` to `streamsize`.
