Hi!

BTW, excuse me if you know already but read_port() is not like a socket or file

will lose data if the bufferSize is too small. You can't read_port() twice on 
the same message.

read_port(port_id id, int32 *protocol, void *msgBuffer, size_t bufferSize);
You are beginning to annoy me! I know what the BeBook says!

So with your code, the receiver better have set a buffersize larger than or 
equal to what the
sender set. This is an ugly dependency. Please don't tell me we can solve it 
with pretty
documentation :-)
No? How is it then, that you know that? Hmmm... from the BeBook? Yes, I think so!

IMO, the solution is to dynamically resize the receive buffer if necessary...
IMO, Marc's opinion, and in others' ones the solution is not to allocate a buffer each time a message is received but to reuse the first, the only, the last allocated buffer.
Please understand that!
I would also want what you want. Believe me! But memory allocation/deallocation operations must be a few, especially on such a port_write/read intensive program like app_server is.

You can call port_buffer_size() to find out the size of the message before 
read_port();
ssize_t port_buffer_size(port_id id);
Oh wow! " that's news to me! :-|".
Please don't start teaching me! I know what there is to know about the work I'm doing.



Adi.
