error export DLL __stdcall

See more:

DLL

Can you please answer on my question about DLL functions export? I have tricky error and don't know how to resolve it.

I have DLL file with functions:

#include <winsock2.h>
#include <iostream>
#include <stdio.h>

using namespace std;

#define EXPORT(RETTYPE) extern "C" __declspec( dllexport ) RETTYPE __stdcall

EXPORT(HANDLE) rpc(LPCWSTR s, int p);
EXPORT(int) rpd(HANDLE h);
EXPORT(int) rpps(HANDLE h, LPCWSTR sp);
EXPORT(int) rppsl(HANDLE h, LPCWSTR sp);
EXPORT(int) rppf(HANDLE h, LPCWSTR sf);


EXPORT (HANDLE) rpc(LPCWSTR s, int p)
{
    HANDLE p;
    p = malloc(sizeof(SOCKET_HANDLE));
    if (p == NULL) return NULL;

    PSOCKET_HANDLE h;
    h= (PSOCKET_HANDLE)p;

    WSADATA     wsaData;

    h->caSize = sizeof(h->ca);
    int Ret;

...
}

EXPORT (int) rpps(HANDLE p, LPCWSTR s)
{
    PSOCKET_HANDLE h = (PSOCKET_HANDLE)p;
    if (h == NULL) return -1;

...
}


EXPORT(int) rppf(HANDLE p, LPCWSTR s)
{
    PSOCKET_HANDLE h = (PSOCKET_HANDLE)p;
    if (h== NULL) return -1;

...
}

And i have console exe file that use this dll(VS C++ 2010 Express both DLL and exe, both unicode, non CLI):

#include <windows.h>
#include <iostream>
#include <stdio.h>
#include <tchar.h>

using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{
HINSTANCE hDLL = LoadLibrary(L"mydll.dll");

if(hDLL == NULL)
{
    printf("Error!");
    return 1;
}

typedef HANDLE(*fnRPC)(LPCWSTR s, int p);
fnRPC rc;
rpc=(fnRPC)GetProcAddress(hDLL,"rpc");

typedef int(*fnRPD)(HANDLE h);
fnRPD rd;
rpd=(fnRPD)GetProcAddress(hDLL,"rpd");

typedef int(*fnRPPS)(HANDLE h, LPCWSTR s);
fnRPPS rpps;
rpps=(fnRPPS)GetProcAddress(hDLL,"rpps");

typedef int(*fnRPPSLF)(HANDLE h, LPCWSTR s);
fnRPPSLF rppslf;
rppslf=(fnRPPSLF)GetProcAddress(hDLL,"rppslf");

typedef int(*fnRPPF)(HANDLE h, LPCWSTR s);
fnRPPF rppf;
rppf=(fnRPPF)GetProcAddress(hDLL,"rppf");

    gets_s(s);
    char p[255];
    printf("\n\n ----Type number and press Enter to continue\n\n");
    gets_s(p);
    HANDLE h = rpc((LPCWSTR)s, atoi(p));

        result = rpps(h, (LPCWSTR)"text");

        getchar();

        result = rppf(h, (LPCWSTR)"text\n text\n text\n text\n text\n text\n text\n text\n text\n text\n text\n text\n text\n text\n text\n text\n text\n text\n");

....

All function are exported throught .def file too:

LIBRARY  sdll
EXPORTS
	rpc	@1
	rpd	@2
	rpps	@3
	rppsl	@4
	rppf	@5

It's compiled normally. But I have error when I call the dll's function (rppf) - Unhandled exception at 0x01071220 in CWRPRNcon.exe: 0xC0000005: Access violation.

This error occurs only when I call this function. All functions before it(rpc,rpps) works without errors. And when I remove __stdcall from dll #define I have no errors at all! When i type it back then I have error again.
Can you please help me to resolve this? I try to but I can't.

P.S. updated question
