what is the following type
 

Hi,

I am looking at some source code and in one file there is the following
definition :

typedef enum _EXCEPTION_DISPOSITION {
ExceptionContinueExecution,
ExceptionContinueSearch,
ExceptionNestedException,
ExceptionCollidedUnwind,
ExceptionExecuteHandler
} EXCEPTION_DISPOSITION;

typedef EXCEPTION_DISPOSITION EXCEPTION_ROUTINE (
struct _EXCEPTION_RECORD *ExceptionRecord,
void *EstablisherFrame,
struct _CONTEXT *ContextRecord,
struct _DISPATCHER_CONTEXT *DispatcherContext
);
typedef EXCEPTION_ROUTINE *PEXCEPTION_ROUTINE;

EXCEPTION_ROUTINE __C_specific_handler;

I am puzzled by the EXCEPTION_ROUTINE definition, it looks like a
function pointer but without the *. Is it a function pointer ?

Hum actually I think it's a function type ... Someone to confirm ?

It looks more like C than C++. The naming conventions are also
illegal, resulting in a lot of undefined behavior (both in C and
in C++). However...

No. It's a function (type). You can use it to declare
functions, but not to define them. Thus, __C_specific_handler
is an (extern) function, or it would be if the name didn't
trigger undefined behavior.
