Mac OS X

[Peter Van Epp]

	It appears OS X is unhappy about looking up 0.0.0.0 with gethostbyname.
What we do about it I'm not sure ...

OS X:

1685          if ((alist = argus_nametoaddr(str)) != NULL)  {
(gdb) 
argus_nametoaddr (name=0xbfffe71b "0.0.0.0") at ./argus_filter.c:4476
4476       if ((hp = gethostbyname(name)) != NULL) {
(gdb) 
4488          return 0;
(gdb) 
4489    }
(gdb) print hp
$7 = (struct hostent *) 0x0
(gdb) s
RaParseCIDRAddr (str=0xbfffe71b "0.0.0.0") at ./ramon.c:1698
1698             error++;
1685          if ((alist = argus_nametoaddr(str)) != NULL)  {
(gdb) 
argus_nametoaddr (name=0xbfffe71b "0.0.0.0") at ./argus_filter.c:4476
4476       if ((hp = gethostbyname(name)) != NULL) {
(gdb) 
4488          return 0;
(gdb) 
4489    }
(gdb) print hp
$7 = (struct hostent *) 0x0
(gdb) s
RaParseCIDRAddr (str=0xbfffe71b "0.0.0.0") at ./ramon.c:1698
1698             error++;

FreeBSD:

1679             if ((ptr = strchr (str, '/')) != NULL) {
(gdb) 
1685          if ((alist = argus_nametoaddr(str)) != NULL)  {
(gdb) 
argus_nametoaddr (name=0xbfbfe8af "255.255.255.255") at ./argus_filter.c:4476
4476       if ((hp = gethostbyname(name)) != NULL) {
(gdb) 
4482          for (p = (unsigned int **)hp->h_addr_list; *p; ++p)
(gdb) 
4483             NTOHL(**p);
(gdb) 
4482          for (p = (unsigned int **)hp->h_addr_list; *p; ++p)
(gdb) print hp
$1 = (struct hostent *) 0x281340b0
