function casting

[Robert P. Clark]

How do I cast something to a pointer to a function that returns
an integer?  I'm trying to save the old function, so that I can
call my own function and then chain to the original.


One of my (failed) attempts has been


main()
{
  int  (*f)();
  char *foo();


    f = ((*int)())foo();  /*  foo returns char*, but I know this is  */
                          /*  really an address of a function        */
}
