Summary
-------

Add IPC shared memory between Main process and these forks (TASK)

Type             : Request
Priority         : Medium
Gambas version   : Master
Product          : Language


Description
-----------

Hello,

I would communicate between the Main Process and all these TASK (Forks) in the both ways in Gambas.
I know and I use since long time communication serialized between Task and the Main Process through Events and it works very fine.

I found on internet a example of this king of bilateral communication here that could be interesting:

Do you think that is possible to implement it in Gambas TASK please ?

Thank you

Olivier
