Detailed Description

template<typename T>
class L4::Ipc::Msg_ptr< T >

Pointer to an element of type T in an Ipc::Istream.

This wrapper can be used to extract an element of type T from an Ipc::Istream, whereas the data is not copied out, but a pointer into the message buffer itself is returned. With is mechanism it is possible to avoid an extra copy of large data structures from a received IPC message, instead the returned pointer gives direct access to the data in the message.

See msg_ptr().
