哪错了 ???

Question

 我初学结构体,不知道下面哪错了,请指教
struct ClientRequest
{
int a;
int b;
int c;
};
ClientRequest Request;
ClientRequest.a=1;
ClientRequest.b=2;
ClientRequest.c=3;
memset(sendBuf,&Request,sizeof(Request));
send(client_sock,sendBuf,sizeof(sendBuf)+1, 0 );

Answer 1

我看来看去你这句就是错的.struct 
{ 
int a; 
int b; 
int c; 
}ClientRequest,*LPClientRequest;
 
ClientRequest Request; 
ClientRequest.a=1; 
ClientRequest.b=2; 
ClientRequest.c=3; char *buf = &ClientRequest
send(client_sock,buf,sizeof(ClientRequest), 0 ); 

Answer 2

纠正一下.char *buf = &ClientRequest 
应该是:
char *P = (char *)&ClientRequest;
接收的话是:
ClientRequest Request; 
 char *P = (char *) &Request;int len = sizeof(Request);
  while(len){
    int ret = recv(sock_client, P, len, 0);
    if(SOCKET_ERROR == ret){
      count<<"Thread:"<<GetCurrentThreadId()<<" recv过程发生错误:"<<WSAGetLastError()<<endl;
      break;
    }
    if(!ret){
      count<<"Thread:"<<GetCurrentThreadId()<<" recv过程发生中连接已断开!"<<endl;
      break;
    }
    len -= ret;
    P += ret;
    if(len == 0)
      cout<<"Thread:"<<GetCurrentThreadId()<<" received from:"<<sock_client<<": A.head="<<A.head<<endl;
  }
