MEMORY Store the credential in memory

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; }
