c++ - Converting string_view to null terminated c string

Question

How would you convert a std::string_view to a null-terminated c string? I've passed a string_view into a function, and need to pass that into another function, which takes a const char* parameter. However, looking at this documentation for string_view, it says

data() may return a pointer to a buffer that is not null-terminated. Therefore it is typically a mistake to pass data() to a routine that takes just a const CharT* and expects a null-terminated string.

Is there a way to properly get a null-terminated c string from a string_view?
