What do people mean by generic pointers
A pointer to an area of memory (if generic data pointer, rather than function pointer) that may be used for different purposes.
Why is a pointer to void generic
Because it doesn't point to a specific type of data, but can be converted to a pointer to any data type.
Why would someone need pointers to void?
One example is a pointer to the memory returned by malloc(). malloc() doesn't know or care what the memory will be used for. It returns a generic pointer that has type void*. Another example is the array argument passed to qsort().
