How to call std::min() when min has been defined as a macro?

Question

How do I call std::min when min has already been defined as a macro?

Answer 1

Use #undef min in your code, after #include <> directives.

#include <...> // bad header that defines `min` macro
#ifdef min
#undef min
#endif

// rest f code.

Addendum: If you need to keep the value of the min macro afterwards, you can disable its definition temporarily using a non-portable solution on some compilers. For instance, Microsoft's C++ compiler has a push_macro pragma that also seems to be supported by GCC.
