These functions implement the old API to get a list of Kerberos hosts, and are thus similar to the krb5_krbhst_init() functions. However, since these functions returns all hosts in one go, they potentially have to do more lookups than necessary. These functions remain for compatibility reasons.

After a call to one of these functions, hostlist is a NULL terminated list of strings, pointing to the requested Kerberos hosts. These should be freed with krb5_free_krbhst() when done with.

The following code will print the KDCs of the realm “MY.REALM”.

char **hosts, **p;
krb5_get_krbhst(context, "MY.REALM", &hosts);
for(p = hosts; *p; p++)
    printf("%s\n", *p);
krb5_free_krbhst(context, hosts);

The man pages krb5_free_krbhst(3), krb5_get_krb524hst(3), krb5_get_krb_admin_hst(3) and krb5_get_krb_changepw_hst(3) are aliases of krb5_get_krbhst(3).
