How is a field function of a struct allocated in terms of a memory it occupies in a memory segment that's allocated for a struct object?
If I have a struct
and if I do
Would that break the program, because the function pointer stored within the memory space for the struct object is totally nuked by the memset cal?
memset(&a ,0, sizeof(A));
In other words, does the memory space allocated for a struct look anything like this?
memory for the structure object a
memory to store address string points to
memory to store address a function pointer points to the function Func()
How is doing
different from using memset for initialization?
