No, only function *declarations* inside other functions are permitted,
but not function *definitions*.
Thus:
int main(void) {
extern void foo(void);
void();
return 0;
}
is allowed, but:
int main(void) {
void foo(void) {
printf("hello\n");
}
void();
return 0;
}
is not.
>(it has a clear modular reason).
There is a good technical reason why it is not allowed. It makes
function pointers very difficult to implement and unintuitive to use.
Nevertheless, gcc implements it as an extension.
