Free memory inside the enclave

[DylanWang]

Hi, Team.

I'm new to SGX.

I'm not that familiar with the memory management inside the enclave.

Since I use the C++11 feature (like unique_ptr) and class objects in my sample code, how should I free memory? For class objects, some other objects are embedded.

Sample code:

test.h

class{

private:

  ClassA* ca;

  unique_ptr<ClassB> cb;

  unique_ptr<ClassC> cc;

}

test.cpp

ca = new ClassA*(...); // delete?

cb = make_unique<ClassB>(function(...));

cc = make_unique<ClassC>(function(...)); // Do I need to do something for this smart pointer?

Hello DylanWang,

You can use delete to free up memory from the class and unique_ptrs just as you would in non-enclave code.

Refer to the SGX SDK Developer Reference Guide for your OS, section C++ Language Support, for more information.
