Where/how to get the "getline" function if it is missing from stdio.h?

Question

I'm writing a program in C using Code::Blocks 13.12 on Windows 8 (the C compiler is mingw32-gcc). I would like to use the "getline" function but it seems to be missing from the stdio.h. Is there any way to get it except for writing own implementation?

Answer 1

getline is a POSIX function, and Windows isn't POSIX, so it doesn't have some POSIX C functions available.

You'll need to roll your own. Or use one that has already been written.

Answer 2

getline is not a standard C library function. Some implementations (such as gcc) provide it as an extension.

If you're compiling with gcc, you'll need to define the feature macro _GNU_SOURCE in order to make it available for your code:

#define _GNU_SOURCE
#include <stdio.h>
...
getline (...);

EDIT

Hopefully since mingw is a GNU compiler, this should be available for you on windows.
