Only developers creating +C-based Tcl/Tk extensions need to take steps to use the +stubs mechanism with their extensions. +See the \fBTcl_InitStubs\fR page for more information. +.PP +Enabling the stubs mechanism for a Tcl/Tk extension requires the following +steps: +.IP 1) 5 +Call \fBTcl_InitStubs\fR in the extension before calling any other +Tcl functions. +.IP 2) 5 +Call \fBTk_InitStubs\fR if the extension before calling any other +Tk functions. +.IP 2) 5 +Define the USE_TCL_STUBS symbol. Typically, you would include the +-DUSE_TCL_STUBS flag when compiling the extension. +.IP 3) 5 +Link the extension with the Tcl and Tk stubs libraries instead of +the standard Tcl and Tk libraries. On Unix platforms, the library +names are \fIlibtclstub8.1.a\fR and \fIlibtkstub8.1.a\fR; on Windows +platforms, the library names are +\fItclstub81.lib\fR and \fItkstub81.lib\fR. +.SH DESCRIPTION +\fBTk_InitStubs\fR attempts to initialize the Tk stub table pointers +and ensure that the correct version of Tk is loaded. In addition +to an interpreter handle, it accepts as arguments a version number +and a Boolean flag indicating whether the extension requires +an exact version match or not. If \fIexact\fR is 0, then the +extension is indicating that newer versions of Tk are acceptable +as long as they have the same major version number as \fIversion\fR; +non-zero means that only the specified \fIversion\fR is acceptable. +\fBTcl_InitStubs\fR returns a string containing the actual version +of Tk satisfying the request, or NULL if the Tk version is not +acceptable, does not support the stubs mechansim, or any other +error condition occurred. +.SH "SEE ALSO" +\fBTcl_InitStubs\fR +.SH KEYWORDS +stubs |
