Tk_Main

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.

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);
