Description Florian Weimer 2013-11-20 12:21:11 UTC 
The implementation is broken because it is not thread-safe and does not really follow the behavior of the BSD function (the returned string could be destroyed by independent read operations on other streams).

I couldn't find any external users of these functions (as defined in libbsd), so it's probably safer to remove these functions.

fparseln could be implemented directly on top of getline because it does not return the pointer obtained from fgetln.
