DESCRIPTION
       Tcl_GetVersion should be used to query the version number of the Tcl library  at  runtime.   This  is
       useful  when  using  a  dynamically  loaded Tcl library or when writing a stubs-aware extension.  For
       instance, if you write an extension that is linked against the Tcl stubs library, it could be  loaded
       into  a  program  linked  to an older version of Tcl than you expected.  Use Tcl_GetVersion to verify
       that fact, and possibly to change the behavior of your extension.

       Tcl_GetVersion accepts NULL for any of the arguments. For instance if  you  do  not  care  about  the
       patchLevel of the library, pass a NULL for the patchLevel argument.
