[SOLVED] Interprocess communication question

tuxuser1 · 12-08-2021, 03:37 AM

Hi,

I'm writing a daemon which populates a data structure (actually it's a real struct type).
Now, there are other little programs (client) which could want read and write on this struct which is located in memory.
You can see this daemon as a server which can access to this little data base.
I'm reading the pipe, named pipe, shared memory, socket etc etc.
Which is the best solution for this use case?
Any advices?

Regards

there is no best solution. It always depends on the actual use cases, the structure of database, the amount of data and other details.

The data base is a simple struct type which contains an array.
The client could be update, remove or add the array entries.
Each array entry is basically another struct type which contains strings, boolean value etc etc....for which i think that the amount the data is very small.
For "the best solution", I mean the appropriate solution.
I don't know what else i have to add to define this use case...

I don't know if I understand the question. Are you asking the best way to write an in-memory data structure store?

The best solution is to use an already written, tested, and documented solution, such as Redis.

I resolved in other way.
The daemon can expose some functions via DBUS.
Mark as solved.
Thanks all
