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. + +.SH KEYWORDS +version, patchlevel, major, minor, alpha, beta, release + |
