So my question is the degree to which gdomap and gdnc are indeed
necessary
for an application not requiring explicit use of inter- process comms and
if NSMessagePortNameServer would address this (since I see NSMessagePorts
are explictly excluded on the MinGW port).
Is it, or would it be, possible to build GNUstep's gui with a ./ configure
option or use an NSUserDefault to limit notifications and objects to the
running GNUstep application and not attempt to connect to the gdomap &
gdnc servers and if so, any hints on implementing this?
Hi,
What do other Windows apps typically use for interprocess communication?
I
know there has been some discussion on this before, but if the current
approach is a big stumbling block for deployment, does anyone think this
could be pressed into service for some of the DO stuff? I know there is
COM
et al. which might be too high-level for the socket-com types of things
GNUstep does, but maybe there is some protocol that COM uses underneath?
For example, I seem to recall gnuclient uses something called 'mailboxes'
(which despite the name have little to do with email) to communicate with
a
running Emacs instance on the WinNT family. This doesn't require any sort
of user interaction, though the situation differs from what you are after
since Emacs just starts the listener every time it starts up.
Everything I've read suggests that windows messages are the best mechanism
for host-local IPC (NSMessagePort).
For instance the WM_COPYDATA should be usable to transfer data from one app
to another.
Each GNUstep app starts up an invisible window to handle events for
NSRunLoop .... this could be given a globally unique name, and used to
send/receive messages.
The NSMessagePortNameServer code could use the windows registry to map port
names to the globally unique names used to identify the windows used in each
app to send messages.
See http://www.codersource.net/mfc_ipc_wm_copydata.aspx for an example.
