Does it mean, that to create shared Mutex or shared Socket for
example, I have to use next construction:

shared Socket socket = cast(shared Mutex)(new Socket());

shared Mutex m = cast(shared Mutex)(new Mutex());


Given the lack of shared constructors, yes - though you should 
probably write

it more like

auto mutex = cast(shared)new Mutex;
auto socket = cast(shared)new Socket;

since then you don't have to worry about accidentally changing 
the base type
(like you did with the Socket), and you don't have to write the 
type multiple

times.

Thank you!  Now my app works fine.

how to use shared keyword in 2.063 version?

2013-05-31 Thread Andrey 

Hello!

I'm trying to use following code:

==
//...

class A
{
private
{
int m_someVar = 10;
}

public
{
this()
{
}
}
}


int main(string[] args)
{
shared A a = null;
a = new shared(A)(); // error.

return 0;
}
==

And on compile time, the compiler says Error: non-shared method 
main.A.this is not callable using a shared object.
How can I use an objects as shared, which classes were not 
defined with synchronized or shared keyword?



Thanks.

To create a shared object you need shared this ctor.

immutable this() for immutable,

and const this() for const.

Check out the change log.  #2 on the list.
