Tk_InitStubs(interp, version, exact)
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_InitStubs page for more information.
- Tcl_Interp *interp (in)
Tcl interpreter handle.
- char *version (in)
A version string consisting of one or more decimal numbers
separated by dots.
- int exact (in)
Non-zero means that only the particular 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
Enabling the stubs mechanism for a Tcl/Tk extension requires the following
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 version 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.
Call Tcl_InitStubs in the extension before calling any other
Call Tk_InitStubs if the extension before calling any other
Define the USE_TCL_STUBS symbol. Typically, you would include the
-DUSE_TCL_STUBS flag when compiling the extension.
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 libtclstub8.1.a and libtkstub8.1.a; on Windows
platforms, the library names are
tclstub81.lib and tkstub81.lib.
