opengl glutmainloop()

Question

i just started off using OpenGL and it seems it is not easy to understand the working of the glutMainLoop() what really happens there? Does it stay there doing

Answer 1

It is exactly as StrixVaria has stated.

glutMainLoop enters the GLUT event processing loop. This routine should be called at most once in a GLUT program. Once called, this routine will never return. It will call as necessary any callbacks that have been registered.
