How to return an array as table from C function to lua? -

i need impelement c function lua script call.i shall return array table function.i used code blow crashed.could tell me how use it?

  struct point {     int x, y; } typedef point point;   static int returnimageproxy(lua_state *l) {     point points[3] = {{11, 12}, {21, 22}, {31, 32}};      lua_newtable(l);      (int = 0;  3; i++) {         lua_newtable(l);         lua_pushnumber(l, points[i].x);         lua_rawseti(l, -2, 2*i+1);         lua_pushnumber(l, points[i].y);         lua_rawseti(l, -2, 2*i+2);         lua_settable(l,-3);     }      return 1;   // want return lua table :{{11, 12}, {21, 22}, {31, 32}} }  

need change lua_settable @lhf mentions. also, adding first 2 indices of sub-tables

typedef struct point {     int x, y; } point;   static int returnimageproxy(lua_state *l) {     point points[3] = {{11, 12}, {21, 22}, {31, 32}};      lua_newtable(l);      (int = 0; < 3; i++) {         lua_newtable(l);         lua_pushnumber(l, points[i].x);         lua_rawseti(l, -2, 1);         lua_pushnumber(l, points[i].y);         lua_rawseti(l, -2, 2);          lua_rawseti(l, -2, i+1);     }      return 1;   // want return lua table :{{11, 12}, {21, 22}, {31, 32}} }
