NAME

krb5_get_krbhst, krb5_get_krb_admin_hst, krb5_get_krb_changepw_hst, krb5_get_krb524hst, krb5_free_krbhst — lookup Kerberos KDC hosts

LIBRARY

Kerberos 5 Library (libkrb5, -lkrb5)

SYNOPSIS

#include <krb5/krb5.h>

krb5_error_code
krb5_get_krbhst(krb5_context context, const krb5_realm *realm, char ***hostlist);

krb5_error_code
krb5_get_krb_admin_hst(krb5_context context, const krb5_realm *realm, char ***hostlist);

krb5_error_code
krb5_get_krb_changepw_hst(krb5_context context, const krb5_realm *realm, char ***hostlist);

krb5_error_code
krb5_get_krb524hst(krb5_context context, const krb5_realm *realm, char ***hostlist);

krb5_error_code
krb5_free_krbhst(krb5_context context, char **hostlist);

DESCRIPTION

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.

EXAMPLES

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);
