Quoting [Andrei Hutanu] (Nov 22 2005):
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..
No, you are probably right. IIRC, we pinned down two different semantics for one step read: a) size is known, malloc by application (buffer) = read (handle = NULL, size); b) size unknown, malloc by implementation (buffer, size) = read (); Thanks, Andre.
Andrei
