Returning function pointer type

Question

Often I find the need to write functions which return function pointers. Whenever I do, the basic format I use is:

typedef int (*function_type)(int,int);

Answer 1

You can probably do something like:

int foo (char i) {return i*2;}

int (*return_foo()) (char c)
{
   return foo;
}

but god, I hope I'll never have to debug you code....
