DESCRIPTION

     The krb5_init_context() function initializes the context structure and reads the configuration file
     /etc/krb5.conf.

     The structure should be freed by calling krb5_free_context() when it is no longer being used.

     krb5_init_context() 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].

     krb5_init_ets() adds all com_err(3) libs to context.  This is done by krb5_init_context().

     krb5_add_et_list() adds a com_err(3) error-code handler func to the specified context.  The error handler
     must generated by the the re-rentrant version of the compile_et(1) program.  krb5_add_extra_addresses() add
     a list of addresses that should be added when requesting tickets.

     krb5_add_ignore_addresses() add a list of addresses that should be ignored when requesting tickets.

     krb5_get_extra_addresses() get the list of addresses that should be added when requesting tickets.

     krb5_get_ignore_addresses() get the list of addresses that should be ignored when requesting tickets.

     krb5_set_ignore_addresses() set the list of addresses that should be ignored when requesting tickets.

     krb5_set_extra_addresses() set the list of addresses that should be added when requesting tickets.

     krb5_set_fcache_version() sets the version of file credentials caches that should be used.

     krb5_get_fcache_version() gets the version of file credentials caches that should be used.

     krb5_set_dns_canonize_hostname() sets if the context is configured to canonicalize hostnames using DNS.

     krb5_get_dns_canonize_hostname() returns if the context is configured to canonicalize hostnames using DNS.

     krb5_get_kdc_sec_offset() returns the offset between the localtime and the KDC's time.  sec and usec are
     both optional argument and NULL can be passed in.

     krb5_set_config_files() set the list of configuration files to use and re-initialize the configuration from
     the files.

     krb5_prepend_config_files() parse the filelist and prepend the result to the already existing list pq The
     result is returned in ret_pp and should be freed with krb5_free_config_files().

     krb5_prepend_config_files_default() parse the filelist and append that to the default list of configuration
     files.

     krb5_get_default_config_files() get a list of default configuration files.

     krb5_free_config_files() free a list of configuration files returned by krb5_get_default_config_files(),
     krb5_prepend_config_files_default(), or krb5_prepend_config_files().

     krb5_set_use_admin_kdc() sets if all KDC requests should go admin KDC.

     krb5_get_use_admin_kdc() gets if all KDC requests should go admin KDC.

     krb5_get_max_time_skew() and krb5_set_max_time_skew() get and sets the maximum allowed time skew between
     client and server.
