is this the example you speak of? If so, cygwin works fine with it.
#include <stdio.h>
#include <stdlib.h>
#include <sys/socket.h>
#include <netinet/in.h>
int
make_socket (uint16_t port)
{
int sock;
struct sockaddr_in name;
/* Create the socket. */
sock = socket (PF_INET, SOCK_STREAM, 0);
if (sock < 0)
{
perror ("socket");
exit (EXIT_FAILURE);
}
/* Give the socket a name. */
name.sin_family = AF_INET;
name.sin_port = htons (port);
name.sin_addr.s_addr = htonl (INADDR_ANY);
if (bind (sock, (struct sockaddr *) &name, sizeof (name)) < 0)
{
perror ("bind");
exit (EXIT_FAILURE);
}
return sock;
}
----------------------------
Compile and run this. You then have 20 seconds ( sleep(20)) when you
can run 'netstat -an | grep 54000' which should show the socket
listening on 54000.
TCP 0.0.0.0:54000 0.0.0.0:0 LISTENING
------
#include <stdio.h>
#include <stdlib.h>
#include <sys/socket.h>
#include <netinet/in.h>
int make_socket(uint16_t port);
int main(void)
{
int socka = 0;
int mysock = 0;
mysock = make_socket(54000);
printf("mysock[%d]\n", mysock);
return(0);
}
int make_socket(uint16_t port)
{
int sock;
struct sockaddr_in name; /* Create the socket. */
sock = socket(PF_INET, SOCK_STREAM, 0);
if (sock < 0)
{
perror("socket");
exit(EXIT_FAILURE);
} /* Give the socket a name. */
name.sin_family = AF_INET;
name.sin_port = htons(port);
name.sin_addr.s_addr = htonl(INADDR_ANY);
if (bind(sock, (struct sockaddr *) &name, sizeof(name)) < 0)
{
perror("bind");
exit(EXIT_FAILURE);
}
sleep(20);
return sock;
}
