      idn2_check_version - API function

      #include <idn2.h>

      const char * idn2_check_version(const char * req_version);

      const char * req_version
                  version string to compare with, or NULL.

      Check IDN2 library version.  This function can also be used to read
      out the version of the library code used.  See IDN2_VERSION for a
      suitable  req_version string, it corresponds to the idn2.h header file
      version.  Normally these two version numbers match, but if you are
      using an application built against an older libidn2 with a newer
      libidn2 shared library they will be different.

      Return value: Check that the version of the library is at minimum the
      one given as a string in  req_version and return the actual version
      string of the library; return NULL if the condition is not met.  If
      NULL is passed to this function no check is done and only the version
      string is returned.
