Cast a vector of std::string to char***

Question

I have an API function that expects a char*** parameter and want to pass a vector. Are there member functions of std::string

Answer 1

"Are there member functions of std::string that let me do that?"

In short: No.

That std::vector stores the std::string instances in a contiguous array, doesn't mean that the pointers to the underlying char arrays of these string instances appear contiguously in memory.
