Function pointer prototype interpretation

[Alfonso Morra]

Hi all,

I came accross this FP signature and it has me baffled.

Can anyone explain this signature to me - i.e what are the input and
output types ?

void(*(*foo)(int))(int,void(*)(int))

Thanks

Did you try cdecl?

[x0030819 asic Linux ~]: cdecl
Type `help' or `?' for help
cdecl> explain void(*(*foo)(int))(int,void(*)(int))
declare foo as pointer to function (int) returning pointer to function
(int, pointer to function (int) returning void) returning void
cdecl> quit

cdecl <<EOD
explain void(*(*foo)(int))(int,void(*)(int))
quit
EOD

declare foo as pointer to function (int) returning pointer to function
(int, pointer to function (int) returning void) returning void

foo -- foo
*foo -- is a pointer
(*foo)() -- to a function
(*foo)(int) -- taking one int parameter
*(*foo)(int) -- returning a pointer
(*(*foo)(int))() -- to a function
(*(*foo)(int))(int, void(*)(int)) -- taking two parameters,
one int and the other
a pointer to a function
taking one int parameter
and returning void
void (*(*foo)(int))(int, void(*)(int)) -- returning void

To summarize, foo is a pointer to a function that returns a pointer to
a function that returns void.

foo -- foo
*foo -- is a pointer
(*foo)() -- to a function
(*foo)(int) -- taking one int parameter
*(*foo)(int) -- returning a pointer
(*(*foo)(int))() -- to a function
(*(*foo)(int))(int, void(*)(int)) -- taking two parameters,
one int and the other
a pointer to a function
taking one int parameter
and returning void
void (*(*foo)(int))(int, void(*)(int)) -- returning void

To summarize, foo is a pointer to a function that returns a pointer to
a function that returns void.
