runtime function giving the version (as a string)

Runtime description of the version of the library
I am using JsonCPP in a program (like RefPerSys) following GNU conventions on Linux. When running as ./refpersys --version that program gives the version of all relevant runtime libraries.

Describe the solution you'd like
Some extern "C" const char* jsoncpp_give_runtime_version(void); function returning the runtime semantic version of the library.

Describe alternatives you've considered
Using macros like JSONCPP_VERSION_STRING is less accurate. It gives the version at compile time of my refpersys executable, and with dynamic linking the runtime library version could have evolved.

Thanks for JSONCPP
Please ask any more details to me (Basile Starynkevitch, in France) by email to basile.starynkevitch@cea.fr (office, at CEA LIST) or basile@starynkevitch.net (home, near Paris, France)

Start by locating the JSONCPP_VERSION_STRING definition and the library's public version declarations. Determine where the requested extern "C" entry point belongs and how its returned semantic version should reflect the dynamically linked library. Done means the public function is available at runtime and returns the library version independently of the caller's compile-time macro.
