问题描述

我有一个接收器缓冲区，我在其中接收来自recv()的数据；打电话给我想从recv()接收数据后清除缓冲区；调用缓冲区.

I have a receiver buffer in which i am receiving data from the recv(); call i want to clear the buffer after receiving data from the recv(); call in to the buffer.

#define DEFAULT_BUFLEN 512
char recvbuf[DEFAULT_BUFLEN];

int recvbuflen = DEFAULT_BUFLEN;
char common[276];
int main()
{

//After connect and send call...
iResult = recv(ThreadSocket, recvbuf, recvbuflen, 0);
            if ( iResult&gt;0 )
              {
for(int j=0;j<=iResult;j++)
common[j]=recvbuf[j];

//NOW I WANT TO CLEAR recvbuf.......
//fflush can't be used,how can i do so?

}

请用伪代码告诉

Please tell by pseudo code

推荐答案

memset(recvbuf, 0, sizeof(recvbuf));

会做的.

will do the job.

正如 Graham Breach 所指出的那样，您将使用此类代码来覆盖common缓冲区.

As already noted by Graham Breach you are going to overrun the common buffer with such code.
