不懂WSASend

[wqrz_015]

int WSASend(
SOCKET s,
LPWSABUF lpBuffers,
DWORD dwBufferCount,
LPDWORD lpNumberOfBytesSent,
DWORD dwFlags,
LPWSAOVERLAPPED lpOverlapped,
LPWSAOVERLAPPED_COMPLETION_ROUTINE lpCompletionRoutine
);

(1) 第3个参数是什么意思？MSDN里写dwBufferCount
[in] Number of WSABUF structures in the lpBuffers array.
是lpBuffers的大小吗？英语不过关


（2）如果想用WSASend发送“abcdefg”该怎么写？按格式下面的写：
char buf[1024]="abcdefg";
send(hSocket,buf,strlen(buf),0);

1.WSASend一次可以发送若干个WSABUF.dwBufferCount就是WSABUF的个数
2.用WSASend可以这样写
WSABUF DataBuf;
DataBuf.len=strlen(buf);
DataBuf.buffer=buf;
DWORD dwSentBytes=0;
if (WSASend(hSocket, &DataBuf, 1, &dwSentBytes, 0, NULL, NULL) == SOCKET_ERROR)
{
//如果发送错误
}
