int luaopen_mylib(lua_State *L);

static int l_sin (lua_State *L)

{

double d=luaL_checknumber(L, 1);

lua_pushnumber(L, sin(d));

//printf(“ok now is  luahook!\n”);

return 1;

}

static const luaL_Reg mylib[]=

{

,

{NULL, NULL}

};

 int luaopen_mylib(lua_State *L)

{

  luaI_openlib(L, “mylib”, mylib, 0);

return 1;

}
