@JamesWidman @joe @euneuber FILE is not required to be a complete type, so that code might not work everywhere.
It also would only work if you gave it a dereferenced char at the start of the array, not any old pointer.

@thephd @joe @euneuber TIL that the definition of "lvalue" was modified to "an expression with [...] a complete object type" sometime after C99 (in which the definition didn't mention completeness), thus rendering expressions like &*p ill-formed when typeof(*p) is incomplete
