bind error during socket programming

Posted on 16th Feb 2014 by admin

i am kinda new to socket programming. wrote the below code for a server. but getting the bind error everytime. i even tried changing the port number(currently is 13 daytime) but doesnt work. please suggest.

#include"header.h"

int main(int argc,char **argv)
{
int listenfd,connfd,retbind;
struct sockaddr_in servaddr;
char buff[MAX];
time_t ticks;

if((listenfd=socket(AF_INET,SOCK_STREAM,0))<0)
{
printf("socket error");
exit(1);
}
bzero(&servaddr,sizeof(servaddr));
servaddr.sin_family=AF_INET;
servaddr.sin_addr.s_addr=htonl(INADDR_ANY); //instead of this use
servaddr.sin_port=htons(13);

if((retbind=bind(listenfd,(struct sockaddr *)&servaddr,sizeof(servaddr)))<0)
{
printf("bind error %dn",retbind);
exit(1);
}
listen(listenfd,1024);
for(;
{
connfd=accept(listenfd,(struct sockaddr *) NULL,NULL);
ticks=time(NULL);
snprintf(buff,sizeof(buff),"%srn",ctime(&ticks));
write(connfd,buff,strlen(buff));
close(connfd);
}
return 0;
}
