sqlite extension is broken about wax HOT 1 CLOSED

another nifty snippet since extension does not support variables binding: string escaping

static int conn_escape(lua_State *L)
{
// From lua kepler project
    BEGIN_STACK_MODIFY(L);
    const char *from = luaL_checkstring(L, 1);
    char *escaped = sqlite3_mprintf("%q", from);
    if (escaped == NULL)
    {
        lua_pushnil(L);
    }
    else
    {
        lua_pushstring(L, escaped);
        sqlite3_free(escaped);
    }
    END_STACK_MODIFY(L, 1);
    return 1;
}

from wax.
