Can you show us a minimal program that exhibits this behavior? The
function seems to work as expected here. The only case where the format
you describe is used is with AF_INET6 addresses, which is not a bug AFAIK.
For instance, the following program:
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>
#include <err.h>
#include <stdio.h>
#include <stdlib.h>
#define BUFLEN 100
int
main(void)
{
struct in_addr ia;
char buf[BUFLEN];
ia.s_addr = htonl(0x7f000001);
if (inet_ntop(AF_INET, &ia, buf, BUFLEN - 1) == NULL)
err(1, "inet_ntop");
printf("inet: %s\n", buf);
return EXIT_SUCCESS;
}
Prints the following output (note that the inet6 address output is probably
an invalid address but still gets printed in the usual format):
$ ./foo
inet: 127.0.0.1
$
Are you sure you're calling inet_ntop() as you should?
