return_internal_reference or return_value_policy
Hi all: I have a small C code, and want to extent it using boost.python. This code return pointer and take pointer as argument. I try to use return_internal_reference or return_value_policy with manage_new_object. Then compiler can\'t give me a object code. I can\'t read these message, does any people can help me ??? I use the bjam in example/tutorial/Jamfile with modify in unix #include <boost/python.hpp> using namespace boost::python; typedef unsigned int *Handle; Handle cr(inti, Handle s) { Handle r; r = new unsigned int[i]; for ( int j = 0; j < i; j++) r[j] = s[j]; return r; } void dr(Handle s) { delete [] s; } void set(int i, Handle r) { r[i] = (unsigned int) i; } int get(int i, Handle r) { return r[i]; } BOOST_PYTHON_MODULE(my) { def(\"cr\",cr,return_value_policy< manage_new_object> () ); // def(\"cr\",cr,return_internal_reference<2> () ); def(\"dr\",dr); def(\"set\",set); def(\"get\",get); } }
