difference between these two struct definitions

[oo]

Hello

What is the difference between these two struct definitions ?

-------------------------header.h
---------------------------------------
struct A{
int a;
int b;
struct B
{
int (*fp1)(void);
int (*fp2)(void);
} *pb;
};

and

------------------------- another header.h
---------------------------------------
struct B
{
int (*fp1)(void);
int (*fp2)(void);
} ;

struct A{
int a;
int b;
struct B *pb;
};

Thank you in advance.

In C, nothing. In C++, the inner struct gets the name A::B in
one case and B in the other.

struct A{
(...)
struct B
{
(...)
int (*fp2)(void);
} *pb;
};

and

struct B
(...)
} ;
struct A{
(...)
struct B *pb;
};
