As the subject says, I would like to pass around an array of
functions. The trick is, that the functions have different type
signatures. Is there a way to put the two functions
int foo(int a, int b);
bool bar(bool a, bool b);
into one array, that I can pass around and cast as necessary?
Thanks, Evan
Have functions in the array without parpameters that call the function
with the applicable parameters, e.g. int foo(int a, int b) or bool
bar(bool a, bool b). That doesn't address the problem of the different
return types (int and bool). So change the return type to void and
return the value as an inout parameter.
You could convert your functions to return via an out parameter (either
manually or with template magic) then have an array of same-signatured
closures that can call any function.
