c++ - Will unique_ptr take control of any pointer it is passed, regardless of how it was created? -


i have been doing std::vector of unique_ptrs:

m_stuff.push_back(std::unique_ptr<thing> (new derivedthing()));

this gives me automatic memory deletion when elements in vector removed.

i have scenario whereby else creates heap memory via new , generic pointer exists. now, suppose this:

    m_stuff.push_back(std::unique_ptr<thing> (thingy));     //thingy thing*

can safely assume this, vector m_stuff has control on thingy such when removed vector, deleted? of course, there possibility of dangling pointer if thingy copied or stored elsewhere different issue.

unique_ptr has nothing magical in it. has jus regular constructor (actually has few) takes pointer of type t , becomes responsible deleting pointee. yes, not care (and can't care) did pointer came from

keyboard - C++ GetAsyncKeyState alternative -

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua
