Pyste for now has manual support for smart pointers. Suppose:

struct C

{

int value;

};

boost::shared_ptr<C> newC(int value)

{

boost::shared_ptr<C> c( new C() );

c->value = value;

return c;

}

void printC(boost::shared_ptr<C> c)

{

std::cout << c->value << std::endl;

}

</pre></code>

To make <tt>newC</tt> and <tt>printC</tt> work correctly, you have to tell Pyste that a

convertor for <tt>boost::shared_ptr<C></tt> is needed.

C = Class('C', 'C.h')

use_shared_ptr(C)

Function('newC', 'C.h')

Function('printC', 'C.h')

</pre></code>

For <tt>std::auto_ptr</tt>'s, use the function <tt>use_auto_ptr</tt>.

This system is temporary, and in the future the converters will automatically be

exported if needed, without the need to tell Pyste about them explicitly.

<a name="holders"></a><h2>Holders</h2>

If only the converter for the smart pointers is not enough and you need to

specify the smart pointer as the holder for a class, use the functions

<tt>hold_with_shared_ptr</tt> and <tt>hold_with_auto_ptr</tt>:

hold_with_shared_ptr(C)

Function('newC', 'C.h')

Function('printC', 'C.h')

</pre></code>
