Typedefinition interchange in two header files

I have two header files that should use typedefs of each other. Here is the situation:

For example:

In header file server.h

typedef struct
{
   int myint;
}ServerSelfData;

typedef struct
{
   ServerSelfData servData;
   ClientSelfData clData;
}SERVER_Data;

Into the second header file called client.h we have:

typedef struct
{
   int myint;
}ClientSelfData;

typedef struct
{
   ClientSelfData clData;
   ServerSelfData servData;
}CLIENT_Data;

So during the compilation there will be error in one of these definitions. In which one depends on which file is included first.

Is there any workaround/solution of this problem?

The definitions of ServerSelfData and ClientSelfData could me moved to separate header files (or one separate header file) which would be included in both server.h and client.h.

Before these header files, you can declare the structs. Later complete the struct with a name.

typedef struct ServerSelfData ServerSelfData;
typedef struct CLIENT_Data CLIENT_Data;

typedef struct ServerSelfData
{
   int myint;
}ServerSelfData;
