@Foxner for example Linux's modules usually provide development headers linked to linux's ABI so you don't have to rewrite it manually at assembly level.

I'm reading that Windows graphics drivers must support universal entry points, that are then called from GDI. You're saying a third party software could call those directly without having to use GDI?

You are using an API? Or just native c++

You can always do that. But I wouldn't recommend it. Just use GDI+ on windows if you don't have very specific needs.

Well... the audio and video driver are actually written with SDL.

C++, sadly. I dislike it but I won't write a complex software without a reasonable level of abstraction.

Ok thanks

can someone explain why this code fails:

vector<int> vec1,vec2; cout << "Enter elements of first vector: (ctrl+D to to end.)\n"; copy(istream_iterator<int>{cin}, istream_iterator<int>{}, back_inserter(vec1)); cout << "Enter elements of second vector. (ctrl+D to end.)\n"; copy(istream_iterator<int>{cin}, istream_iterator<int>{}, back_inserter(vec2));

Ah, but you need to use win32api to call the DeviceIoControl function, to talk to the driver ... :-P

For the below function 'f ' does return a vector from a function causes any problem? vector<int> f(){ vector<int> v; v.push_back(1); return v; }

For the below function 'f ' does return a vector from a function causes any problem? vector<int> f(){ vector<int> v; v.push_back(1); return v; }

should work right

Doesn't v goes out of scope while returning and what we are left with is nothing?

Doesn't v goes out of scope while returning and what we are left with is nothing?

no, u returning the object(copy) from function, main v vector will be destroyed

So, all the dynamically allocated elements for v inside f are copied back to the vector that is catching this in main?

in main u probably wrote std::vector<int> name = f(); f returns copy of v name will use a copy for it's own copy constructor

"use copy for it's own copy constructor"?

"use copy for it's own copy constructor"?

yes, do u know about constructor types ?

and is it shallow or deep?

are the elements again allocated somewhere else?

are the elements again allocated somewhere else?

elements of copy ?

elements of copy ?

what?

what?

it's temp object, using for creating name with copy constructor, that's all

copy then will be destroyed

it's temp object, using for creating name with copy constructor, that's all

must be deep copy. Ain't it?

Ok what ever it is . You mean the entire vector is copied again to some other memory location and named as "name". isn't it?

yes, think about it like a process, u using f(), it returns a copy, then name using it for it's own construction

int a[50], size, insert, i, pos, choice, del, count = 0, key; paste this into main

int a[50], size, insert, i, pos, choice, del, count = 0, key; paste this into main

Redefination of insert as different kind of symbol

`void create(); void insert(); void del(); void search(); void display();` if u are declaring functions before their using, there is no need th.eir declarations

Same error

1 thing if u want to change ur current array with size, u need to use another one(temp arr)
