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
#include <krb5.h> 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()).
