sokcet小疑点，让大家见笑了

sokcet小问题，让大家见笑了
这是个很间的socket tcp通信，没有使用select模式，其中IP和端口号都已经写死了，问题是在服务器端，没有打印，它就接收不到数据，recv是个阻塞函数
这个问题，我原来好像遇到过，现在又遇到有点小郁闷，有谁知道的啊，给我解答下，谢谢了
client：
#include <netinet/in.h> // for sockaddr_in
#include <sys/types.h> // for socket
#include <sys/socket.h> // for socket
#include <stdio.h> // for printf
#include <stdlib.h> // for exit
#include <string.h> // for bzero
#include <errno.h>
#include <arpa/inet.h>
int main(int argc , char** argv)
{
  int iclient_socket = socket(PF_INET,SOCK_STREAM,0);
  if(-1 == iclient_socket ) 
  {
  perror("create socket fail");
  return -1;
  }  
 
  struct sockaddr_in client_addr;
  bzero(&client_addr,sizeof(client_addr));
  client_addr.sin_family = AF_INET;
  client_addr.sin_addr.s_addr = htons(INADDR_ANY);
  client_addr.sin_port = htons(0);

  if( -1 == bind(iclient_socket,(struct sockaddr*)&client_addr,sizeof(client_addr)))
  {

  exit(1);
  }

exit(1);
  }
  server_addr.sin_port = htons(10242);
  socklen_t sock_length = sizeof(server_addr);
  
  if( 0 > connect(iclient_socket,(struct sockaddr*)&server_addr,sock_length) )
  {
  printf("connect error\n");
  }
  else
  {
  printf("connect success\n");
  }
  while(1)
  {
  char chbuffer[256] = {0};
  scanf("%s",chbuffer);
  ssize_t sendcount = send(iclient_socket,chbuffer,sizeof(chbuffer),0);

  printf("send error\n");

printf("send success\n");
}
  }
  //close(iclient_socket);

}


重点在server：
#include <netinet/in.h> // for sockaddr_in
#include <sys/types.h> // for socket
#include <sys/socket.h> // for socket
#include <stdio.h> // for printf
#include <stdlib.h> // for exit
#include <string.h> // for bzero
#include <errno.h>
int main()
{
  int iserver_socket = socket(PF_INET,SOCK_STREAM,0);
  if( -1 == iserver_socket )
  {
  printf("create socket fail,erroNO:%d<----->%s",errno,strerror(errno));
  }
   
  //bind socket
  struct sockaddr_in server_addr;
  bzero(&server_addr,sizeof(server_addr)); 
  server_addr.sin_family = AF_INET;
  server_addr.sin_addr.s_addr = htons(INADDR_ANY);
  server_addr.sin_port = htons(10242); 
  if( -1 == bind(iserver_socket,(struct sockaddr *)&server_addr,sizeof(server_addr)))
  {
  perror("bind error");
  }

  //listen
  if( -1 == listen(iserver_socket,1))
  {
  printf("listen fail,errorNO:%d",errno);
  }  
 
struct sockaddr_in client_addr;

  int ilength = sizeof(client_addr);
   
  int icurrent_socket =accept(iserver_socket,(struct sockaddr *)&client_addr,(socklen_t *)&ilength);
if( -1 == icurrent_socket )
{
printf("accept error,erroNO:%d",errno);
}
  else
{
printf("------------>connect success<---------------------\n");
}
while(1)
{
//receive
//printf("front recv\n"); -------------->这里不打印，就会接收不到数据，重点
char chbuffer[256]={0};  
int irecvlength = recv(icurrent_socket,chbuffer,sizeof(chbuffer),0);
if( -1 == irecvlength )
{
printf("recvive error,errNO:%d",errno);
}
else if( 0 < irecvlength )
{
printf("have recv");
}
else
{
printf("recv ===0");
}
printf("----->%s<-----",chbuffer);
}
   
//close(icurrent_socket);
//close(iserver_socket);
  return 0;
}



[解决办法]
try to:
printf("----->%s<-----",chbuffer);
->
printf("----->%s<-----\n",chbuffer);

楼上正解，缓冲区没有被刷新，默认为全缓冲，所以在你打印之后由于缓冲区被newline刷新，所以连带上一次接受的字符一起输出
