I am getting the feeling that, one thread is spawn internally for accepting connections and main thread is for processing those connections, that makes it total two threads, correct me if I am...

Hello Guys,
I need help in implementing asynchronous single threaded TCP server using boost asio.. Any example or link will be highly appreciated..

Thanks

Hello,
Do you guys know why this does not compile?
<code>
std::for_each(v.begin(), v.end(), &boost::algorithm::to_lower<string>);
</code>
v is a vector of strings that I want to convert to...

Thanks man..Thats what even I concluded..

class BASE
{
public:
virtual bool isEqual(const BASE& rhs) const = 0;
};

class Derived: public BASE

Hello Guys,

I have to implement a class BASE which is abstarct and has a function called isEqual which ofcourse checks for equality..

Now isEqual has to be pure virtual.

Now bunch of derived...

Hello,
Anybody have any idea why this is the signature.



size_t copy ( char* s, size_t n, size_t pos = 0) const;

of std::string.copy function.

I mean why char* s should it not have been...

class TestClass
{
public:
TestClass(string name, string profession): _name(name), _profession(profession)

Compilar is looking for a overload in the class, which it does not finds.
and errors out..Because you can not over load a member function with a global function..

Use this...


::write_binary( n, f );

1. If I was to design, I would not keep data member in Abstract Class, which is Item.

2. I will keep class hierarchy something different, and not based on Item but based on type.

For example...

What is tthis doing in your code?



delete [] this->dataptr;
size=source.size;
dataptr=0

1. Role of constructor is to initialize and not destruct....

First thing..
Why following does not work?


c=c+d;


because here c+d will return object of type A.
While c is object of type B.

If you have to find whether there is a NULL.

You could do soemthing like the following..

char buffer[1000000] = {'\0'};
....
bool detected = strlen(buffer) < 1000000;
I think...

Thats called constructor initialization list.
This will ensure that all the data member are initialized before you hit constructor body.

If you dont do that, all the data mambers will be...

Hello guys,
I am trying to write a code to find out no of characters in a multibyte UTF8 encoded string.



#include<stdio.h>
#include <stdlib.h>
#include <iostream>
#include <sstream>...

So what is the problem?

Moreover, if you passing big vectors around..Better use reference to pass around Vectors..

>>Unless the write operation is atomic.

And how could it be atomic in STL map..?? Ofcourse when not properly synchronized...

All I can say is revisit your design..

With this current design you can hardly do much.

See...Your threads must be running on some condition...

something like this..


void svc()
{
while(isRunning)
{
//do something.

No No..

Here you are exposing RunIt just as a test hook. I want no test hook.

If you do that any production code could define RunIt and will start accessing private data/member function.

Hello Guys,

I want to access private function from outside of the class..
I know its not allowed. But the thing is I need to test private function.

I need some kind of hack, because its not a...

Hello Guys,

I am facing a strange problem.

My shell file build.sh contains



g++ -o Client *.cpp -I ../ace5.5.static -lACE -L ../ace5.5.static/ace

And now what I am gonna do with void* obj..? KHI KHI KHI KHI...:):)

yup...Common base class is nessessary in that case..
