Andre, Thanks for the notes!
- read: two step mechanism: (int handle, int size) = query_size (); (char* buffer) = read (handle, size);
- handle can be zero, if size is known (one step read) - buffer needs to be allocated by application. - if size is zero, the buffer is allocated by the implementation and returned to be freed by the application (one step read)
This part is a bit confusing .. with the one step read you lose the length of the message? it should probably be (char* buffer, int size) = read () for the one step read ..Or am I reading it wrong.. Andrei
