I am getting a “memcpy is not defined in this scope error” with the following piece of code:

CommonSessionMessage::CommonSessionMessage(const char* data, int size) 
    : m_data(new char[size]) {
  memcpy(m_data.get(), data, size);
}

I have looked through this site and google and could not find a solution that would resolve the issue for me.

Any assistance would be appreciated.

Thank you.
