Re: [Dev-C++] Dev-cpp support for getline

[Michael C U. <mu...@cb...>]

Dave,

getline() does not exist in the mingw32 port of GCC (it is a GNU specific
extension that is not part of ISO C).

Your best bet is fgets() if you want to make sure that you cannot cause a
buffer overflow when reading in data.
