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;
}
