Erlang, C, IC and asyncronous servers/clients
Wed Feb 21 21:57:26 CET 2001
The current IC-system seems to generated code only for cases, were
communication is initiated from only one side. I would need to port
some older code, which used IG in more asynchronous way (yes, I know,
it was not completely safe).
In detail I have
Erlang side C side
raw telemetry -> data processing, packet detection
when packet found from raw telemetry
<- up to N packets
C-process receives binary chunks from Erlang, whenever it finds a
valid, complete packet, it sends it to Erlang-process for further
distribution. The catch is, there's n packets to generate, so simple
function return values is not adequate.
At least the IC examples for C-server and -client don't allow this kind
of two-way message sending.
So to put it simply, is there a way to do it ?
(and yes, the I could the processing in Erlang, but we also have to
give out source code for colleagues to analyze data later. Erlang is
used in real time situation )
