#include <iostream>
#include <string>
#include <cstring>
int main(void)
{
char* i = new char(10);
memset(i, 0, 10);
strcpy(i, "hello!");
std::string s=i;
delete [] i;
std::cout << s << std::endl;
return 0;
}
tyler@tangerine:~$ g++ poc.cpp
tyler@tangerine:~$ ./a.out
hello!
tyler@tangerine:~$
so... It -is- copying, as I said earlier.
the std::string manages it's own array, so it can expand and etc. A smart
pointer won't do any good as it's not used after the strcpy, thus deleting
it has no affect here.
Thanks,
Ty
