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.
