NAME
       krb5_ccache_intro - The credential cache functions

Kerberos credential caches
       krb5_ccache structure holds a Kerberos credential cache.

       Heimdal support the follow types of credential caches:

       o SCC Store the credential in a database

       o FILE Store the credential in memory

       o MEMORY Store the credential in memory

       o API A credential cache server based solution for Mac OS X

       o KCM A credential cache server based solution for all platforms

   Example
       This is a minimalistic version of klist:

       #include <krb5.h>

       int
       main (int argc, char **argv)
       {
           krb5_context context;
           krb5_cc_cursor cursor;
           krb5_error_code ret;
           krb5_ccache id;
           krb5_creds creds;

           if (krb5_init_context (&context) != 0)
               errx(1, 'krb5_context');

           ret = krb5_cc_default (context, &id);
           if (ret)
               krb5_err(context, 1, ret, 'krb5_cc_default');

           ret = krb5_cc_start_seq_get(context, id, &cursor);
           if (ret)
               krb5_err(context, 1, ret, 'krb5_cc_start_seq_get');

           while((ret = krb5_cc_next_cred(context, id, &cursor, &creds)) == 0){
               char *principal;

               krb5_unparse_name(context, creds.server, &principal);
               printf('principal: %s\n', principal);
               free(principal);
               krb5_free_cred_contents (context, &creds);
           }
           ret = krb5_cc_end_seq_get(context, id, &cursor);
           if (ret)
               krb5_err(context, 1, ret, 'krb5_cc_end_seq_get');

           krb5_cc_close(context, id);

           krb5_free_context(context);
           return 0;
       }
