pointer to pointer and unique_ptr [duplicate]

This question already has an answer here:

• Proper way to create unique_ptr that holds an allocated array 5 answers
• Is there any use for unique_ptr with array? 16 answers

ALL,

There are plenty of examples on the web about using smart pointers with one level of indirection. I.e.:

char *p = new char;
unique_ptr<char> p;
p = std::make_unique<char>();

Those 3 lines above are the same - one is using old style pointer with new the other 2 are using C++11 smart-pointer.

However, I wasn't able to find an example on how to convert (what should be the syntax) for

char **p;
p = new char*;
p[0] = new char[15];

Is going to be

unique_ptr<unique_ptr<char> > p;

auto temp = std::make_unique<char>();
p = std::make_unique<>( p );

Could someone please help?

TIA!
