WSARecv出错,,,好心人帮个忙

Question

我拦截迅雷的WSARecv后，,, 迅雷就出错了,自动退出,,而且nReturn =WSARecv(返回的是-1;
怎么解决这个问题呢?
int WINAPI MyWSARecv(
SOCKET s, 
LPWSABUF lpBuffers,
    DWORD dwBufferCount,
LPDWORD lpNumberOfBytesRecvd,
    LPDWORD lpFlags,
LPWSAOVERLAPPED lpOverlapped,
    LPWSAOVERLAPPED_COMPLETION_ROUTINE lpCompletionRoutine 
)
{    int nReturn;
    HookOffOne(&WSARecvapi);
   nReturn =WSARecv(s, lpBuffers, dwBufferCount,lpNumberOfBytesRecvd,lpFlags,lpOverlapped,lpCompletionRoutine);
//Sleep(su);
//len1=nReturn;
    HookOnOne(&WSARecvapi);    char *tmpbuf=new char[*lpNumberOfBytesRecvd+100];
    memset(tmpbuf, 0, sizeof(tmpbuf));
    sprintf(tmpbuf, "WSASend|%d|%d|%s",
            GetCurrentProcessId(),
            lpNumberOfBytesRecvd,
            lpBuffers->buf);
   sndmsg(tmpbuf);
    delete tmpbuf;
    return(nReturn);   
}

Answer 1

你想查迅雷的数据传送速度,写个socks5代理,在本机启用,直接将迅雷经过代理,让代理帮你统计还省事.

Answer 2

 我拦截WSARecv  得到的lpNumberOfBytesRecvd 是几个亿甚至几十亿,,,该怎么办?

Answer 3

下面返回的是-1,,,,如何解决?nReturn =WSARecv(s, lpBuffers, dwBufferCount,lpNumberOfBytesRecvd,lpFlags,lpOverlapped,lpCompletionRoutine);

Answer 4

异步接收返回－1是很正常的，需要进一步用GetLastError来判断，决定下面的处理。

Answer 5

int WINAPI MyWSARecv(
 SOCKET s, 
 LPWSABUF lpBuffers,
 DWORD dwBufferCount,
 LPDWORD lpNumberOfBytesRecvd,
 LPDWORD lpFlags,
 LPWSAOVERLAPPED lpOverlapped,
 LPWSAOVERLAPPED_COMPLETION_ROUTINE lpCompletionRoutine 
 )
{

    int nReturn;
    HookOffOne(&WSARecvapi); //Sleep(su);
nReturn =WSARecv(s, lpBuffers, dwBufferCount,
lpNumberOfBytesRecvd, lpFlags, lpOverlapped, lpCompletionRoutine);
if(nReturn == SOCKET_ERROR)
{
if(WSAGetLastError() != WSA_IO_PENDING)
return nReturn; if(!WSAGetOverlappedResult(s, lpOverlapped, lpNumberOfBytesRecvd, TRUE, lpFlags))
return SOCKET_ERROR;
}

len1=nReturn;
    HookOnOne(&WSARecvapi);

/* char *tmpbuf=new char[*lpNumberOfBytesRecvd+100];
    memset(tmpbuf, 0, sizeof(tmpbuf));
    sprintf(tmpbuf, "WSASend|%d|%d|%s",
GetCurrentProcessId(),
lpNumberOfBytesRecvd,
lpBuffers->buf);
sndmsg(tmpbuf);
    delete tmpbuf;*/
    return(nReturn);   
}
