Newbie... trying to bring interactivity in C application using LUA...!!

Dear Sir,

I am trying to bring some interactivity to my c appliaction,

To begin with, I am trying to draw a rectangle which is defined in Gui.c from LUA in my application Application_main.c.

Gui.c

/*structure actually defined in Gui.h*/

typedef struct {

char R;

char G;

char B;

} Gui_color_t;

Int Gui_Draw_Rectangle( x,y,Width,Height, (Gui_color_t *)color){

******Some code*******

}

SCSL_Draw_Rect(lua_State*L)

{

GUI_Color_t asvDrawColor = {31, 31, 0};

int i,j[4];

int n = lua_gettop(L);

for (i = 1; i <= n; i++){

if (!lua_isnumber(L, i)){

lua_pushstring(L, "incorrect argument");

lua_error(L);

}

j[(i-1)] = lua_tonumber(L, i);

printf("from stack %d\n",j[(i-1)]);

}

GUI_DrawRectangle(j[1], j[2], j[3], j[4] &asvDrawColor);

}

Application_main.c

Int Lua_main( void )

{

int error;

lua_State *L = lua_open(); /* opens Lua */

luaL_Reg Creg;

lua_Integer n;

luaL_openlibs(L);

printf("luaL_openlibs\n");

lua_pushcfunction(L, SCSL_Draw_Rect(L));

printf("lua_pushcfunction\n");

/* n = 0;

lua_pushinteger(L, n);*/

n = 100;

lua_pushinteger(L, n);

n = 100;

printf("lua_pushinteger\n");

lua_pushinteger(L, n);

n = 300;

lua_pushinteger(L, n);

n = 300;

lua_pushinteger(L, n);

printf("lua_call\n");

lua_call( L, 5, 0);

printf("lua_call\n");

lua_close(L);

return 0;

}

Int Application_MainEntry ( )

{

********Some code ********

Lua_main();

*******Some Code********

}

I get all the prints in the Lua_main function. I see all the prints on the console but not the rectangle.

Can you help me out in this regard.

Thanks in advance.
