Tcl_Main - main program for Tcl-based applications
Tcl_Main(argc, argv, appInitProc)
Tcl_Main acts as the main program for most Tcl-based applications.
Starting with Tcl 7.4 it is not called main anymore because it
is part of the Tcl library and having a function main
in a library (particularly a shared library) causes problems on many
Having main in the Tcl library would also make it hard to use
Tcl in C++ programs, since C++ programs must have special C++
- 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.
Normally each application contains a small main function that does
nothing but invoke Tcl_Main.
Tcl_Main then does all the work of creating and running a
When it is has finished its own initialization, but before
it processes commands, Tcl_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;
