c++ – Variables auto-initialized to 0 in unnamed namespace? – Stack Overflow
When I have a global function pointer in C I can declare it static and it’s initialized as NULL and only available for my file. In C++ I’m switching a lot of stuff to anonymous namespaces but I’m curious if they hold that same guarantee. If I have a function pointer in an anonymous namespace will it be initialized to null?
Thanks
All variables with static storage duration are zero-initialized when the program starts. These include all variables declared at namespace scope (in the global namespace or in any other namespace, including an unnamed namespace).
