[ros-dev] Send Messages

[James Tabor]

Hi!
The experiment failed. I already tested this last night. We allocate
in co_IntDoSendMessage and doing it again made things worse and the
system ran out of memory. ATM we are eating a lot of page pool and
that is why win32k kicks out before the stack is full, when inside a
message recursion. Still need to reposition IntCallWndProc/Ret when
calling the client.
Thanks,
James
PS. Good info!

Calling the window proc requires to pack the parameters. If we send the message to another process we queue the message and when the other process gets the message, it packs it in order to give it to user mode. ie: packing is only needed when we marshal a message from kernel mode to user mode.
