### NAME

krb5_rd_error, krb5_free_error, krb5_free_error_contents, krb5_error_from_rd_error - parse, free and read error from KRB-ERROR message

### LIBRARY

Kerberos 5 Library (libkrb5, -lkrb5)

### SYNOPSIS

```krb5_error_code` krb5_rd_error(`` ```krb5_context context` ```const krb5_data *msg` ```KRB_ERROR *result` )
```void` krb5_free_error(`` ```krb5_context context` ```krb5_error *error` )
```void` krb5_free_error_contents(`` ```krb5_context context` ```krb5_error *error` )
```krb5_error_code` krb5_error_from_rd_error(`` ```krb5_context context` ```const krb5_error *error` ```const krb5_creds *creds` )

### DESCRIPTION

Usually applications never needs to parse and understand Kerberos error messages since higher level functions will parse and push up the error in the krb5_context. These functions are described for completeness.

krb5_rd_error(``) parses and returns the kerboeros error message, the structure should be freed with krb5_free_error_contents(``) when the caller is done with the structure.

krb5_free_error(``) frees the content and the memory region holding the structure iself.

krb5_free_error_contents(``) free the content of the KRB-ERROR message.

krb5_error_from_rd_error(``) will parse the error message and set the error buffer in krb5_context to the error string passed back or the matching error code in the KRB-ERROR message. Caller should pick up the message with krb5_get_error_string(```3`) (don't forget to free the returned string with krb5_free_error_string(``)).
