Void is a kind of non-type used when performing certain typeless operations.
Also, when a function doesn''t return a value, it is said to return void, because it literally returns nothing.
Void pointers can be used when passing data to a nonoverloaded function that needs to accept multiple types of data, as in a file i/o function or network send/recv function. Void pointers can be cast to other types of pointers, and vice versa, but you may not, IIRC, dereference a void pointer.
Corrections welcome.
Peace,
