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;
}
