Convert the getaddrinfo() error code to a Kerberos et error code.

Parameters

eai_errno contains the error code from getaddrinfo().
system_error should have the value of errno after the failed getaddrinfo().

Returns

Kerberos error code representing the EAI errors.

KRB5_LIB_FUNCTION krb5_error_code KRB5_LIB_CALL krb5_err (krb5_context context, int eval, krb5_error_code code, const char * fmt, ...)

Log a warning to the log, default stderr, include bthe error from the last failure and then exit.

Parameters

context A Kerberos 5 context
eval the exit code to exit with
code error code of the last error
fmt message to print

KRB5_LIB_FUNCTION krb5_error_code KRB5_LIB_CALL krb5_errx (krb5_context context, int eval, const char * fmt, ...)

Log a warning to the log, default stderr, and then exit.

Parameters

KRB5_LIB_FUNCTION void KRB5_LIB_CALL krb5_free_error_message (krb5_context context, const char * msg)

Free the error message returned by krb5_get_error_message().

Parameters

context Kerberos context
msg error message to free, returned byg krb5_get_error_message().

KRB5_LIB_FUNCTION const char* KRB5_LIB_CALL krb5_get_error_message (krb5_context context, krb5_error_code code)

Return the error message for `code' in context. On memory allocation error the function returns NULL.

Parameters

context Kerberos 5 context
code Error code related to the error

Returns

an error string, needs to be freed with krb5_free_error_message(). The functions return NULL on error.

KRB5_LIB_FUNCTION char* KRB5_LIB_CALL krb5_get_error_string (krb5_context context)

Return the error message in context. On error or no error string, the function returns NULL.

Parameters

context Kerberos 5 context

Returns

an error string, needs to be freed with krb5_free_error_message(). The functions return NULL on error.

KRB5_LIB_FUNCTION krb5_log_facility* KRB5_LIB_CALL krb5_get_warn_dest (krb5_context context)

Get the default logging facility.

Parameters

context A Kerberos 5 context

Convert the gethostname() error code (h_error) to a Kerberos et error code.

Parameters

eai_errno contains the error code from gethostname().

Returns

Kerberos error code representing the gethostname errors.
