Creating a class member pointer function variable that points to a non-static class member function

Tag : cpp , By : Bharath
Date : March 29 2020, 07:55 AM
Does that help The goal is to have the member variable _AddValue point to the CreateFirstValue function upon class initialization and after the first invocation of AddValue, all future calls to it will invoke CreateAnotherValue. ,

help you fix your problem
How does the base class BnSurfaceTexture know the function "requestBuffer"?
class Base
    virtual void f() { /* Base */ } // could be pure virtual
    virtual void g() { f(); };

class Derived: public Base
    virtual void f() { /* derived */ }
Base* pB = new Derived;

How to order below code : a class member function calling a non-member function with class argument?

Hope that helps It might be better to illustrate the problem with below code: , You can forward-declare structs and classes. So:
struct Sales_data;
std::istream& read(std::istream& is, Sales_data& item);

Javascript class member function calling member function by setInterval, couldn't access member variable

I hope this helps . setInterval() doesn't work with this. See here: https://developer.mozilla.org/en-US/docs/Web/API/WindowTimers/setInterval#The_this_problem
function job_queue(){
    this.job = null;
    this.pointer = this.job;
    this.job_dispatcher = null; 
    this.length = 0;
job_queue.prototype.add_job = function( job ){
    if( this.job == null ){
        this.job = {
        this.pointer = this.job;
        this.length = 1;
        this.pointer.next = { 
        this.pointer = this.pointer.next;

job_queue.prototype.event_handler = function(){
        if( typeof this.job['job'] == 'undefined'){
        if( this.job.job != null ){
            this.job = this.job.next();


job_queue.prototype.start_dispatch = function(){
    var self = this;
    if( this.job_dispatcher == null ){
        console.log( this.event_handler );
        this.job_dispatcher = setInterval( function(){self.event_handler()},1000);

var jq = new job_queue();
function a(){
function b(){

Invalid use of non-static member function - Class Member Function Calling Another Class Member Function

Tag : cpp , By : Matt Croydon

fixed the issue. Will look into that further void(*task_main)() is expecting a pointer to a function. You attempt to feed it void otherMain(); which is a class method and has a hidden this parameter.
This stuff gets a little whacky. Here is a great write-up on some of the badness and how to avoid it.
class taskRunner
    virtual execute() = 0;
    static void task_runner(void * userparam)
        taskRunner* task = (taskRunner*)userparam;
void otherMain()
    printf("Hello multitasking world!"); 
    yield(); // a free function that calls into the system's TaskManager to preempt
