You can't use fclose on stdin, stdout, or stderr. And there's no point in closing them when you're duplicating over them anyway, so just remove those altogether.
This likely isn't related to the error, but open() does not return 0 on error, it returns -1. Check if fd<0.
You should also close the original fd of anything you're duplicating once you're done copying it.

tk_main
Tk_Main(3) Tk Library Procedures Tk_Main(3)
__________________________________________________________________________________________________________________________________________________
NAME
Tk_Main - main program for Tk-based applications
SYNOPSIS
#include <tk.h>
Tk_Main(argc, argv, appInitProc)
ARGUMENTS
int argc (in) Number of elements in argv.
char *argv[] (in) Array of strings containing command-line arguments.
Tcl_AppInitProc *appInitProc (in) Address of an application-specific initialization procedure. The value for this argument is
usually Tcl_AppInit.
_________________________________________________________________
DESCRIPTION
Tk_Main acts as the main program for most Tk-based applications. Starting with Tk 4.0 it is not called main anymore because it is part of
the Tk library and having a function main in a library (particularly a shared library) causes problems on many systems. Having main in the
Tk library would also make it hard to use Tk in C++ programs, since C++ programs must have special C++ main functions.
Normally each application contains a small main function that does nothing but invoke Tk_Main. Tk_Main then does all the work of creating
and running a wish-like application.
When it is has finished its own initialization, but before it processes commands, Tk_Main calls the procedure given by the appInitProc
argument. This procedure provides a "hook" for the application to perform its own initialization, such as defining application-specific
commands. The procedure must have an interface that matches the type Tcl_AppInitProc:
typedef int Tcl_AppInitProc(Tcl_Interp *interp);
AppInitProc is almost always a pointer to Tcl_AppInit; for more details on this procedure, see the documentation for Tcl_AppInit.
