This is moving slowly. I now have RPC caller side support for std::string and
std::vector<char>. RPC server side is next. K.O. |

We are considering to remove the analyzer framework mana.cxx from MIDAS. It
currently has some compiler warnings and we wonder if we should fix them which
would take some time or just remove the file. We have now to much more modern

25 Aug 2024, Adrian Fisher, Info, Help parsing scdms_v1 data?
|
Hi! I'm working on creating a ksy file to help with parsing some data, but I'm having trouble finding some information. Right now, I have it set up very
rudimentary - it grabs the event header and then uses the data bank size to grab the size of the data, but then I'm needing additional padding after the
data bank to reach the next event.

I had two free afternoon and took the opportunity to write a new API for the MSCB
system. I'm not sure if anybody else actually uses MSCB (MIDAS slow control bus),
but anyhow.

Look at the C++ implementation of the MIDAS data file reader, the code is very
simple to follow.
