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.
