Major version number of the Tcl library.

.SH DESCRIPTION
|
||
|
.PP
|
||
|
\fBTcl_GetVersion\fR 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 \fBTcl_GetVersion\fR to verify that fact, and possibly to
|
||
|
change the behavior of your extension.
|
||
|
.PP
|
||
|
\fBTcl_GetVersion\fR accepts NULL for any of the arguments. For instance if
|
||
|
you do not care about the \fIpatchLevel\fR of the library, pass
|
||
|
a NULL for the \fIpatchLevel\fR argument.
