以下内容是关于socket编程的“recv”函数，但是通不过编译，为什么？

Question

#include <stdio.h>#include <winsock.h>#pragma comment(lib,"Ws2_32")#define MAXSIZE 100main(int argc,char *argv[]){int bytenum=0,char buf[MAXSIZE];SOCKET socket_fd;struct sockaddr_in their_addr;WSADATA ws;WSAStartup(MAKEWORD(2,2),&ws);socket_fd=socket(AF_INET,SOCK_STREAM,0);their_addr.sin_family=AF_INET;their_addr.sin_port=htons(830);their_addr.sin_addr.s_addr=inet_addr(argv[1]);bind(socket_fd,(struct sockaddr *)&their_addr,sizeof(struct sockaddr));connect(socket_fd,(struct sockaddr *)&their_addr,sizeof(struct sockaddr));printf("connecting.....");bytenum=recv(socket_fd,buf,MAXSIZE,0);buf[bytenum]='\0';printf("receive %s",buf);closesocket(socket_fd);return 0;}

Answer 1

也已经提示的很清楚了...
你先看一个函数原形吧
int recv(
SOCKET s,
char FAR *buf,
int len,
int flags
);
Parameters
s
[in] Descriptor identifying a connected socket.
buf
[out] Buffer for the incoming data.
len
[in] Length of buf.
flags
[in] Flag specifying the way in which the call is made.

Answer 2

第一个分号该改为逗号
