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.
