*& in declaration

[sem]

I've got a DLL and header file, that contains
extern "C" {
//some other delarations
__declspec(dllexport) int __stdcall myfunc (unsigned char*& p1);
typedef int (__stdcall* PROCESS)(unsigned char*);
}

It's apparently for C++, but I need to use it in C program

I replaced this declaration by
SLIB_API int __stdcall process (unsigned char** p);

Does anybody have an idea why this doesn't work?

Try replacing it with

unsigned char* p1

If that is not it, the only other thing it MIGHT be is

unsigned char p1

I call it as

unsigned char* m = NULL;
int result = process(&m);

Is it correct?

The working C++ code calls it another way:

unsigned char* m = NULL;
int result = process(m);

The problem is that C compiler complains of *& construct. Regards, Dima

C does not understand call by refernece..it is not the C compilers problem to underatnd C++!!!..char c,char &c,char *c,char * &c
C will reject 2,4

@sem:
References are pointers internally.
So it should work if you feed the function an ordinary pointer to a pointer instead a reference to a pointer.
