problems to create the winMessage() function..

[tuxd3v]

hello,
I like the Idea of having a lua newt binding library :)
I am trying to add function WinMessage()

static int L_WinMessage( lua_State *L ) {
	const char * title;
	const char * buttonText;
	const char * text;
	/*int result;*/
	unsigned int width;
	unsigned int height	= 1;
	unsigned int cols	= 20;
	unsigned int result;

	/* Check if they are Strings if yes, return them..*/
	title		= luaL_checkstring( L, 1 );
	buttonText	= luaL_checkstring( L, 2 );
	text		= luaL_checkstring( L, 3 );
	lua_pop( L, 3 );

	width		= strlen( title );
	if( strlen( buttonText ) > width )
		width = strlen( buttonText );
	if( strlen( text ) > width )
		width = strlen( text );

	height = ( width%cols != 0 ) ? ( ( width / cols ) + 1 ) : ( width / cols );

	result = newtCenteredWindow( width, height, title );
	if( ! result  ){
		/* add form, with a label inside and a button at the end..*/

		lua_pushnil( L );
		return 1;
	}else{
		lua_pushboolean( L, result );
	}
	return 1;
}

The problem I know almost nothing about newt Library :(
I am stuck there..

It seems by the 3 examples that maybe I will need a form to put a label inside, and a button at the end..?
I can't write a string to root of Window directly or something close?

Thanks in Advance,
Best Regards,

well, seems that I miss-understand a lot of newt..
The L_WinMessage:

static int L_WinMessage( lua_State *L ) {
	char * title		= NULL;
	char * buttonText	= NULL;
	char * text		= NULL;
	/* Check if they are Strings if yes, return them..*/
	title		= ( char* )luaL_checkstring( L, 1 );
	buttonText	= ( char* )luaL_checkstring( L, 2 );
	text		= ( char* )luaL_checkstring( L, 3 );
	lua_pop( L, 3 );

	newtWinMessage( title, buttonText, text );
	lua_pushnil( L );

	return 1;
}

And it works, I don't know about the string allocation memory and de-allocation?
