C and C++ make a clear-cut distinction between two types of pointers: data pointers and function pointers. A function pointer embodies several constituents such as the list of arguments, a return-to address, and the machine instructions. A data pointer, on the other hand, merely holds the address of the first byte of a variable. The substantial difference between the two functions led the C standardization committee to prohibit the use of void* (or data pointers of any kind) to represent function pointers and vice versa. In C++ this restriction was relaxed, yet the results of coercing a function pointer to a void * are implementation-dependent. The opposite (converting of data pointers to function pointers) is a recipe for a core dump. Also, unlike a data pointer, a function pointer cannot be dereferenced.
