c++ - Can I return a vector to extend an existing vector with C++11? -

this question has answer here:

• how use c++11 move semantics append vector contents vector? 2 answers

what's best way extend vector contents of vector returned function?

i can do:

std::vector<int> base; {     std::vector<int> tmp = getvec(); //rvo make efficient     base.reserve(base.size() + tmp.size());     base.insert(base.end(), std::make_move_iterator(tmp.begin()), std::make_move_iterator(tmp.end())); } 

but possible without creating tmp? pass base in getvec reference, feel parameters should inputs , return value outputs. ideally able do:

base.extend(getvec()); 

but can't see how normal vector functions.

send vector want append parameter. used , accepted.

void func(vector<int>* master) {    // generate values did in getvec() append original vector    // instead of temp.     while(generatingnumbers(i))        master->push_back(i); }
