Reload a json file at runtime without emptying my std::ifstream

Hi !

• Describe the feature in as much detail as possible.

I have to reload a JSON file at runtime. I actually use std::ifstream to open my json file and I fill the json object with the >> operator. I don't want to re-open my file with my ifstream but just set the stream position to 0 using std::ifstream::seekg.
The problem is : When I pass it to json object, my ifstream is empty. Is there a way to build a json object via an ifstream without emptying it ?

Thanks in advance.

Find a way to do it via stringstream.
