-.TH Tk_InitStubs 3 8.4 Tk "Tk Library Procedures"
-.so man.macros
-.BS
-.SH NAME
-Tk_InitStubs \- initialize the Tk stubs mechanism
-.SH SYNOPSIS
-.nf
-\fB#include <tk.h>\fR
-.sp
-const char *
-\fBTk_InitStubs\fR(\fIinterp, version, exact\fR)
-.SH ARGUMENTS
-.AS Tcl_Interp *interp in
-.AP Tcl_Interp *interp in
-Tcl interpreter handle.
-.AP char *version in
-A version string consisting of one or more decimal numbers
-separated by dots.
-.AP int exact in
-Non-zero means that only the particular Tk version specified by
-\fIversion\fR is acceptable.
-Zero means that versions newer than \fIversion\fR are also
-acceptable as long as they have the same major version number
-as \fIversion\fR.
-.BE
-.SH INTRODUCTION
-.PP
-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
-incorporating 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 \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 \fBUSE_TCL_STUBS\fR and the \fBUSE_TK_STUBS\fR
-symbols. Typically, you would include the \fB\-DUSE_TCL_STUBS\fR and
-the \fB\-DUSE_TK_STUBS\fR flags 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 \fIlibtclstub8.4.a\fR and \fIlibtkstub8.4.a\fR; on Windows
-platforms, the library names are \fItclstub84.lib\fR and
-\fItkstub84.lib\fR. Adjust the library names with appropriate version
-number but note that the extension may only be used with versions of
-Tcl/Tk that have that version number or higher.
-.SH DESCRIPTION
-.PP
-\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 mechanism, or any other
-error condition occurred.
