Constructor & Destructor Documentation

request_ptr::request_ptr

(

request *

ptr_ = NULL

)

[inline]

Constructs an request_ptr from request pointer.

request_ptr::request_ptr

(

const request_ptr &

p

Member Function Documentation

bool request_ptr::empty

(

)

const [inline]

Returns true if object is not initialized.

request* request_ptr::get

(

)

const [inline]

Access to owned request object (synonym for operator->() ).

Returns:

reference to owned request object

Warning:

Creation another request_ptr from the returned request or deletion causes unpredictable behaviour. Do not do that!
