KRB5_RD_ERROR(3) Library Functions Manual KRB5_RD_ERROR(3)

krb5_rd_error, krb5_free_error, krb5_free_error_contents, krb5_error_from_rd_errorparse, free and read error from KRB-ERROR message

Kerberos 5 Library (libkrb5, -lkrb5)

#include <krb5.h>

krb5_rd_error(krb5_context context, const krb5_data *msg, KRB_ERROR *result);

krb5_free_error(krb5_context context, krb5_error *error);

krb5_free_error_contents(krb5_context context, krb5_error *error);

krb5_error_from_rd_error(krb5_context context, const krb5_error *error, const krb5_creds *creds);

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.

() 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.

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

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

() 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 (3) (don't forget to free the returned string with ()).
