fopen deprecated warning

by

It looks like Microsoft has deprecated lots of calls which use buffers to improve code security. However, the solutions they’re providing aren’t portable. Anyway, if you aren’t interested in using the secure version of their calls (like fopen_s), you need to place a definition of _CRT_SECURE_NO_DEPRECATE before your included header files. For example:

#define _CRT_SECURE_NO_DEPRECATE
#include <stdio.h>

The preprocessor directive can also be added to your project settings to effect it on all the files under the project. To do this add _CRT_SECURE_NO_DEPRECATE to Project Properties -> Configuration Properties -> C/C++ -> Preprocessor -> Preprocessor Definitions.
