“No previous prototype for function” warning

Question

i use shareKit to myself program .

but in the FBConnectGlobal, there are some warning,

NSMutableArray* FBCreateNonRetainingArray() {
  CFArrayCallBacks c         


        

Answer 1

According to c standard, declaring the prototype as

NSMutableArray* FBCreateNonRetainingArray(void);
//      --------------->                  ^^^^   
// Yes, with the void as the parameter

solves the issue.
