Is there any standard way to load parameters from a file in C++ on Linux?

Question

Imaging that a program needs to know quite a lot of parameters to do its tasks properly, such as 'Port = 2323' this kind of things.

now I want to save these parameters in a plain text file, similar to Unix' system variables such as users and groups.

Is there any standard way/libraries that can help me to do this? Does anyone ever used them before? thanks

Answer 1

Boost.Program_options library. Is this you are looking for?

The program_options library allows program developers to obtain program options, that is (name, value) pairs from the user, via conventional methods such as command line and config file.

Answer 3

You can also create an alias or shell script that executes your program with given parameters. To conviniently get these parameters there's "getopt"
