Prevent certain std functions from being called

Question

For certain reasons we should not use certain std functions like std::sort() in our code base (we have our own implementations for those).

Is there a way to prevent calls to those functions, preferably by raising an error at compile time?

I looked at overriding std functions but it leads to undefined behavior.

Answer 1

You shouldn't try override o change functions in a standard library since in the first case you will have ODR violation and in the second case some of the thirdparties may used in your project may be affected.

I would suggest you to create a custom check for clang-tidy and add a CI job to run it on your codebase. This will take some time but I believe this is the best option.

Answer 2

There's no way you can mark any of the standard functions as unwanted in your code base.

You can do regular code reviews, or use a configurable static analysis tool to check committed code for usage of the unwanted functions though.
The latter only makes sense with an established CI process for your software.
