krb5_get_host_realm - Get the Kerberos realm names for a host.
================================================================
..
.. c:function:: krb5_error_code krb5_get_host_realm(krb5_context context, const char * host, char *** realmsp)
..
:param:
**[in]** **context** - Library context
**[in]** **host** - Host name (or NULL)
**[out]** **realmsp** - Null-terminated list of realm names
..
:retval:
- 0 Success
- ENOMEM Insufficient memory
:return:
- Kerberos error codes
..
Fill in *realmsp* with a pointer to a null-terminated list of realm names. If there are no known realms for the host, a list containing the referral (empty) realm is returned.
If *host* is NULL, the local host's realms are determined.
Use :c:func:`krb5_free_host_realm()` to release *realmsp* when it is no longer needed.
