Thanks all for your answers.

Concerning the OS and the buffer transfert mechanism, as I said, this is 
under control. I use Windows and the WM_COPYDATA message.

My usage is a bit special. The writing process writes a bunch of data in 
a memory buffer then requests this buffer to be transferred to another 
process by way of WM_COPYDATA. The receiving process reads the data from 
the "new" memory buffer. I say "new" since the address is different from 
the one used in the writing process (of course it can not be the same).

The library Jean-Pierre pointed me to perfectly matches this usage. 
Light and easy to use. Thanks.
One enhancement I see is to manage the buffer size to avoid buffer 
overflow (or did I missed something ?).

Thanks again to everybody.

Nicolas
