Detailed Description
Function Documentation
   KRB5_LIB_FUNCTION krb5_error_code KRB5_LIB_CALL krb5_add_et_list
       (krb5_context context, void(*)(struct et_list **) func)
       Add a specified list of error messages to the et	list in	context. Call
       func (probably a	comerr-generated function) with	a pointer to the
       current et_list.

       Parameters
	   context A kerberos context.
	   func	The generated com_err et function.

       Returns
	   Returns 0 to	indicate success. Otherwise an kerberos	et error code
	   is returned,	see krb5_get_error_message().

   KRB5_LIB_FUNCTION krb5_error_code KRB5_LIB_CALL krb5_add_extra_addresses

       client's	address	list when communicating	with the KDC.

       Parameters
	   context Kerberos 5 context.
	   addresses addreses to add

       Returns
	   Returns 0 to	indicate success. Otherwise an kerberos	et error code
	   is returned,	see krb5_get_error_message().

       Returns
	   Returns 0 to	indicate success. Otherwise an kerberos	et error code

	 also present in creds .

        KRB5_TC_MATCH_TIMES_EXACT Compares the	ticket times exactly.

        KRB5_TC_MATCH_TIMES Compares only the expiration times	of the creds.

        KRB5_TC_MATCH_AUTHDATA	Compares the authdata fields.

        KRB5_TC_MATCH_2ND_TKT	Compares  the second tickets (used by user-to-

       Parameters
	   context pointer to returned context

       Returns
	   Returns 0 to	indicate success. Otherwise an errno code is returned.
	   Failure   means   either   that   something	 bad  happened	during
	   initialization (typically ENOMEM) or	that Kerberos  should  not  be
	   used	 ENXIO.	 If  the function returns HEIM_ERR_RANDOM_OFFLINE, the
	   random source is not	available and later Kerberos calls might fail.

       krb5_init_context() will	get one	random byte to make sure our random is
       alive. Assumption is that once the non blocking	source	allows	us  to
       pull bytes, its all seeded and allows us	to pull	more bytes.

       Most  Kerberos users calls krb5_init_context(), so this is useful point
       where we	can do the checking.

       (krb5_context context)
       Returns	the  list of Kerberos encryption types sorted in order of most
       preferred to least preferred encryption type. Note that some encryption
       types might be disabled,	so you need to check with krb5_enctype_valid()
       before using the	encryption type.

       Returns
	   list	of enctypes, terminated	with ETYPE_NULL. Its  a	 static	 array
	   completed  into the Kerberos	library	so the content doesn't need to
	   be freed.

       Returns	 an  the  struct  addrinfo  in	in  that  corresponds  to  the
       information in `host'. free:ing is handled by krb5_krbhst_free, so  the
       returned	ai must	not be released.
