there's not much to see here, sorry.
Wild pointers arise when a pointer is used prior to initialization to some known state, which is possible in some programming languages.
In computing, a null pointer has a value reserved for indicating that the pointer does not refer to a valid object.
An autorelative pointer is a pointer whose value is interpreted as an offset from the address of the pointer itself; thus, if a data structure has an autorelative pointer member that points to some portion of the data structure itself, then the data structure may be relocated in memory without having to update the value of the auto relative pointer.
A function pointer, also called a subroutine pointer or procedure pointer, is a pointer that points to a function. As opposed to referencing a data value, a function pointer points to executable code within memory.
