Is there a cleaner/more idiomatic way to do this?

I'm afraid this is the C idiom for assigning a void pointer to a function pointer:

  *(void **) &fptr = getvoidptr();

Without the silly cast you'd get the following warning when compiling with -Wpedantic:

  warning: ISO C forbids assignment between function pointer and 'void *'

Once you learn the idiom, and the reason behind it, it makes things (slightly) easier to parse than dealing with a bunch of typedefs, IMHO.
