Package: libc6-dev
Version: 2.11.2-10
Severity: normal
Cannot use INADDR_LOOPBACK in a bind call. A code example follows:
server_addr.sin_family = AF_INET;
server_addr.sin_port = htons(tcp_server_port);
server_addr.sin_addr.s_addr = INADDR_LOOPBACK;
... followed by a bind() call fails.
whereas:
server_addr.sin_family = AF_INET;
server_addr.sin_port = htons(tcp_server_port);
server_addr.sin_addr.s_addr = inet_addr("127.0.0.1");
... works.
I printout the two values like below:
printf("server_addr.sin_addr.s_add: %ld INADDR_LOOPBACK: %ld\n",
server_addr.sin_addr.s_addr, INADDR_LOOPBACK);
...and I get:
server_addr.sin_addr.s_add: 16777343 INADDR_LOOPBACK: 2130706433
...which is odd, I guess the two values should be the same.
My includes look like this:
#include <stdio.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <errno.h>
#include <unistd.h>
#include <stdlib.h>
#include <string.h>
#include <netinet/in.h>
...and netinet/in.h is the one include to have INADDR_LOOPBACK defined.
Thanks!

INADDR_LOOPBACK is given in the host representation, it should still be
converted to network representation. Please try with:
server_addr.sin_addr.s_addr = htonl(INADDR_LOOPBACK);
