krb5_creds, krb5_copy_creds, krb5_copy_creds_contents, krb5_free_creds, krb5_free_cred_contents -- Kerberos 5 credential handling functions LIBRARY
Kerberos 5 Library (libkrb5, -lkrb5) SYNOPSIS
#include <krb5.h> krb5_error_code krb5_copy_creds(krb5_context context, const krb5_creds *incred, krb5_creds **outcred); krb5_error_code krb5_copy_creds_contents(krb5_context context, const krb5_creds *incred, krb5_creds *outcred); krb5_error_code krb5_free_creds(krb5_context context, krb5_creds *outcred); krb5_error_code krb5_free_cred_contents(krb5_context context, krb5_creds *cred); DESCRIPTION
krb5_creds holds Kerberos credentials: typedef struct krb5_creds { krb5_principal client; krb5_principal server; krb5_keyblock session; krb5_times times; krb5_data ticket; krb5_data second_ticket; krb5_authdata authdata; krb5_addresses addresses; krb5_ticket_flags flags; } krb5_creds; krb5_copy_creds() makes a copy of incred to outcred. outcred should be freed with krb5_free_creds() by the caller. krb5_copy_creds_contents() makes a copy of the content of incred to outcreds. outcreds should be freed by the called with krb5_free_creds_contents(). krb5_free_creds() frees the content of the cred structure and the structure itself. krb5_free_cred_contents() frees the content of the cred structure.
