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.
