Did you test errno? Please try this:
#include <errno.h>
#include <stdio.h>
#include <string.h>
#include <netinet/in.h>
#include <sys/socket.h>
int
main (int argc, char *argv[])
{
int socket_fd;
struct sockaddr_in sin;
int len, res;
len = sizeof (struct sockaddr_in);
memset (&sin, 0, len);
sin.sin_port = htons (5786);
sin.sin_family = AF_INET;
sin.sin_addr.s_addr = INADDR_ANY;
printf ("sin len %d\n",len);
socket_fd = socket (AF_INET,SOCK_STREAM,0);
res = bind (socket_fd, (struct sockaddr *) &sin, len);
printf ("res = %d, errno = %s\n", res, strerror (res? errno: 0));
return 0;
}
