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  pos-
     sibly 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.
