69.Sh DESCRIPTION
70Usually applications never needs to parse and understand Kerberos
71error messages since higher level functions will parse and push up the
72error in the krb5_context.
73These functions are described for completeness.
74.Pp
75.Fn krb5_rd_error
76parses and returns the kerboeros error message, the structure should be freed with
77.Fn krb5_free_error_contents
78when the caller is done with the structure.
79.Pp
80.Fn krb5_free_error
81frees the content and the memory region holding the structure iself.
82.Pp
83.Fn krb5_free_error_contents
84free the content of the KRB-ERROR message.
85.Pp
86.Fn krb5_error_from_rd_error
87will parse the error message and set the error buffer in krb5_context
88to the error string passed back or the matching error code in the
89KRB-ERROR message.
90Caller should pick up the message with
91.Fn krb5_get_error_string 3
92(don't forget to free the returned string with
93.Fn krb5_free_error_string ) .
