Tk_InitStubs - initialize the Tk stubs mechanism
CONST char *
Tk_InitStubs(interp, version, exact)
Tcl_Interp *interp (in) Tcl interpreter handle.
char *version (in) A version string consisting of one or
more decimal numbers separated by
int exact (in) Non-zero means that only the particu-
lar Tk version specified by version is
acceptable. Zero means that versions
newer than version are also acceptable
as long as they have the same major
version number as version.
The Tcl stubs mechanism defines a way to dynamically bind extensions to
a particular Tcl implementation at run time. the stubs mechanism
requires no changes to applications incoporating Tcl/Tk interpreters.
Only developers creating C-based Tcl/Tk extensions need to take steps
to use the stubs mechanism with their extensions. See the Tcl_Init-
Stubs page for more information.
Enabling the stubs mechanism for a Tcl/Tk extension requires the fol-
1) Call Tcl_InitStubs in the extension before calling any other Tcl
2) Call Tk_InitStubs if the extension before calling any other Tk
2) Define the USE_TCL_STUBS symbol. Typically, you would include the
-DUSE_TCL_STUBS flag when compiling the extension.
3) 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 libtclstub8.4.a and libtkstub8.4.a; on Windows plat-
forms, the library names are tclstub84.lib and tkstub84.lib
(adjust names with appropriate version number).
Tk_InitStubs 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 exact 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 version; non-zero means that only the specified ver-
sion is acceptable. Tcl_InitStubs 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.
