I've searched but couldn't find any results (my terminology may be off) so forgive me if this has been asked before.

I was wondering if there is an easy way to call a void* as a function in C without first declaring a function pointer and then assigning the function pointer the address;

ie. assuming the function to be called is type void(void)

void *ptr;
ptr = <some address>;
((void*())ptr)(); /* call ptr as function here */

with the above code, I get error C2066: cast to function type is illegal in VC2008

If this is possible, how would the syntax differ for functions with return types and multiple parameters?
