The top three is structure variable
Above is for. The Action of assignment card don't know much about



The concept of function Pointers and pointer function I am understand
But this heap together I don't know much about the
Consult everybody small white

CodePudding user response:

The function ArbiterAction () address is assigned to sArbiter. Action

CodePudding user response:

Cast to a function pointer, namely the function of 1/f, said ArbiterAction () address is assigned to sArbiter. Action,
Void (*) () with no parameters of
Void (*) (int, long) containing parameter
Void (*) (void *) containing a pointer parameter
