Subject: RE: Where are the socket libraries?
Date: Fri, 08 Dec 2000 11:33:00 -0000 [thread overview]
Message-ID: <C1AD7DC4C16ED211A82B00A0C9EA52A401EC99F6@re0ma002.teligent.net> (raw)
Hi,
I'll put in my 2 cents on this one. First of all I don't think
"333.444.555.6" is a valid IP address. There may be a conversion problem
w/inet_addr. Also I suspect your assignments of 'serv'. It also appears
that you did not setup the transport end point. You might try this:
#include <sys/socket.h>
#include <netinet/in.h>
#define SvrSocketNo 777
#define SIZE sizeof(struct sockaddr_in)
int sockfd;
char c;
struct sockaddr_in server = {AF_INET, SvrSocketNo};
sockfd = (int)socket(AF_INET, SOCK_STREAM,0);
connect(sockfd, (struct sockaddr *)&server, SIZE);
.
.
.
len = send(sockfd, &c, 1, 0);

Good Luck .. John

The source I have is below:
The error messages I get when trying to gcc this stuff is:
request for member "sin_family" in something not a structure or union
request for member "sin_addr" in something not a structure or union
request for member "sin_port" in something not a structure or union
The only place I can find sin_family and such is on /usr/include/linux/in.h.
I have tried to include <linux/in.h> but it makes no difference. All help
will be appreciated. Thanks
#include <stdio.h>
#include <sys/types.h>
#include <sys/socket.h>
main()
{
int i,j;
int sock1;
char ibuf[BUFSIZ];
struct sockaddr *serv;
memset(&serv,0,sizeof(serv));
serv.sin_family = AF_INET;
serv.sin_addr.s_addr = inet_addr("333.444.555.6");
serv.sin_port = htons(777);
if(connect(sock1, (struct sockaddr*) &serv,sizeof(serv)) < 0)
printf("Error on connect\n");
i = write(sock1,"This is test1",13);
i = read(sock1,ibuf,20);
printf("Ibuf: %s\n",ibuf);
}
