variables - C what is this line of code doing? Is it casting? -

-

so i'm following online tutorial (on os development if matters) , saw line of c code void. here's simplified version:

void function1(struct regs *r) {   void (*handler)(struct regs *r);   // happened here?    // things void *handler }

what happened in line? declared variable

void *handler

but did cast? doesnt seem cast. happened there?

void (*handler)(struct regs *r); declares handler pointer function expects argument of type struct regs * , returns type void.
