Are C++ template-functions threadsafe?

Question

Googling don't find anything. Are they created at point of use, or are the generic parts shared between instances?

(Same for template classes?)

Answer 1

Template functions are created at compile time. The template property is completely orthogonal to thread-safety.

Answer 2

They're no more or less thread-safe than any other type of function.

Answer 3

The only way I can think of thread safety being affected by this is that if someMethod<typename T>() wasn't thread safe then it would still be okay for a thread to operate on someMethod<int>() while another worked on someMethod<std:string>(), as long as the lack of thread-safety didn't come from their both calling into some non-templated function.

The situation where something else is guaranteeing that only one thread is doing a particular task with a particular type at a time seems pretty unlikely though.

Answer 4

Template functions are simply ...templates used by the compiler to generate "normal" functions. So it's the same as normal functions, there is no difference.
