Brent's Encapsulated C Programming Rules (2020)

It's funny. One can't simply write a correct C code. Even after years of practice.

    void strclone(const char* str, char** outCpy)
    {
        size_t len = strlen(s) + 1;
        *outCpy = malloc(len);
        memcpy(outCpy, str, len); // wrong dest address 
    }

I don't like double pointer parameters because of it.
