[SDL] accessing on video surface from two processes.

[Thomas Mueller]

Dear all,

I would like to access a video surface from a second process.

I would like to open a window in a program and leave it open for a
while.

*SDL_SetVideoMode to opens a window and returns a pointer to access that
window. 

How can I "draw things" from a second process on that window opened by
the first process ?

Maybe I'm lacking some very basic understanding of pointers and C/C++
but I would be grateful for a some help.

Thanks Thomas.
