2) lvalue of any type T may be converted to a lvalue or rvalue reference to the same type T, more or less cv-qualified.Likewise, a prvalue of class type or an xvalue of any type may be converted to a more or less cv-qualified rvalue reference. AFAIK casting from (int (*)(int, int)) to (void (*)(void)) and back would be even less-well-defined than to/from void *, and there's no POSIX mmap or dlsym case to protect that usage from wonkiness.union is probably the best bet AFAIK.. Edit: As noted downthread, C99 enables casts between function pointer types. You can't cast a void* to unmanaged memory to a managed . Collection of values placed under one name in a single block of memory Can put structs, arrays in other structs Given a struct instance, access the fields using the '. In lines 17-20, the printf . In this example, the address of person1 is stored in the personPtr pointer using personPtr = &person1;. If malloc() succeeds it will point to an object of type struct point // The type of p has not changed (it's still a pointer to an object of struct point; i.e. void pointer in C - Tutorials Point Posts. C++ Pointer to void (With Examples) - Programiz ("Finished"); return 0;} void ProcessPacket (unsigned char * buffer, int size) {//Get the IP Header part of this packet . #include <iostream> using namespace std; int main() { void* ptr; float f = 2.3f; // assign float address to void pointer ptr = &f; cout << "The content of pointer is . Hey guys. However, you can use a cast to convert a void pointer to any other pointer type, and vice versa. Note the difference between the type casting of a variable and type casting of a pointer. 2 For passing large . It points to some data location in the storage means points to the address of variables. And I figured since . A void pointer is declared like a normal pointer, using the void keyword as the pointer's type: void* ptr; // ptr is a void pointer Additional possibilities include: - the struct is 32 bits but is not properly aligned for access.
