difference between int ** func() and int *& func()

What is the difference between int** func() and int*& func(). Can you please explain it with suitable example.

Thanks,
Devesh.

do you have linux installed. if yes try to use the cdecl utility

this is what i get

cdecl> explain int * *p()
declare p as function returning pointer to pointer to int
cdecl> explain int * &p()
Warning: Unsupported in C -- 'reference'
declare p as function returning reference to pointer to int
cdecl>

so int **func() is a function that returns a pointer to a pointer to int and int * & func() is a function that returns an reference to a pointer to a function, and as seen above the second statement is not supported in C, you can try it in c++ tho.
