aliG4 , what do you really want dude ?

Code:
int main (int argc, char *argv[])

-this are the parameter's of the main function ( here is a function , which return an integer value ).

argc : is the number of argument's passed , beginning with 0.

*argv[0] , *argv[1] .. : the argument's ?

Whtat does this mean ?

Let's say : ./do bla bla

./do is the 0 argument , bla is the first and second bla is the second.

So if you want to have a program do per example . You may want to execute multiple commands , and pass them like argument's.

Let's say , you want do to execute ps comand you may just enter :

Code:
 ./do ps

- if you want do to execute let's say ping command , you can do :

Code:
 ./do ping

suposing , that you have configured in the program ( your C aplication ) to execute argv[1] as a command.

let's say something like system("argv[1]") .. or something like that ?

This is what do you want ? Smilie

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.
