No. A void pointer can only store pointers to object and incomplete
types. Conversion between function and void pointer types is undefined.
Also there is no "generic" function pointer type.

There is no signle "generic" function pointer type. On the other
hand, *any* function pointer type (such as void (*)(void)) may be used
as a generic function pointer type. (It's generic in the sense that
you can losslessly convert any function pointer to and from it; unlike
with void*, such conversions require explicit casts.)
