c++ - How to save a curl download in a std::string?

Question

I know I can call system("curl path-LJO") from a c++ program to download a file and save it in the current directory and then I can use the STL to save it to a std::string. But is there a way to save it directly in a std::string? I know abot https://github.com/curl/curl but I was wondering: is any specifier in the curl command that does that? If not, what would be the best way to approach this?

You need to use the libcurl library in your code. You can use the CURLOPT_READFUNCTION and CURLOPT_READDATA options to setup a callback that saves the received data directly to your std::string variable.
