.Sh DESCRIPTION
|
|
||||||
These functions print a warning message to some destination.
|
|
||||||
.Fa format
|
|
||||||
is a printf style format specifying the message to print. The forms not ending in an
|
|
||||||
.Dq x
|
|
||||||
print the error string associated with
|
|
||||||
.Fa code
|
|
||||||
along with the message.
|
|
||||||
The
|
|
||||||
.Dq err
|
|
||||||
functions exit with exit status
|
|
||||||
.Fa eval
|
|
||||||
after printing the message.
|
|
||||||
.Pp
|
|
||||||
Applications that want to get the error message to report it to a user
|
|
||||||
or store it in a log want to use
|
|
||||||
.Fn krb5_get_error_message .
|
|
||||||
.Pp
|
|
||||||
The
|
|
||||||
.Fn krb5_set_warn_func
|
|
||||||
function sets the destination for warning messages to the specified
|
|
||||||
.Fa facility .
|
|
||||||
Messages logged with the
|
|
||||||
.Dq warn
|
|
||||||
functions have a log level of 1, while the
|
|
||||||
.Dq err
|
|
||||||
functions log with level 0.
|
|
||||||
.Pp
|
|
||||||
.Fn krb5_get_err_text
|
|
||||||
fetches the human readable strings describing the error-code.
|
|
||||||
.Pp
|
|
||||||
.Fn krb5_abort
|
|
||||||
and
|
|
||||||
.Nm krb5_abortx
|
|
||||||
behaves like
|
|
||||||
.Nm krb5_err
|
|
||||||
and
|
|
||||||
.Nm krb5_errx
|
|
||||||
but instead of exiting using the
|
|
||||||
.Xr exit 3
|
|
||||||
call,
|
|
||||||
.Xr abort 3
|
|
||||||
is used.
|
|
||||||
.Pp
|
|
||||||
.Fn krb5_free_error_string
|
|
||||||
frees the error string
|
|
||||||
.Fa str
|
|
||||||
returned by
|
|
||||||
.Fn krb5_get_error_string .
|
|
||||||
.Pp
|
|
||||||
.Fn krb5_clear_error_string
|
|
||||||
clears the error string from the
|
|
||||||
.Fa context .
|
|
||||||
.Pp
|
|
||||||
.Fn krb5_set_error_string
|
|
||||||
and
|
|
||||||
.Fn krb5_vset_error_string
|
|
||||||
sets an verbose error string in
|
|
||||||
.Fa context .
|
|
||||||
.Pp
|
|
||||||
.Fn krb5_get_error_string
|
|
||||||
fetches the error string from
|
|
||||||
.Fa context .
|
|
||||||
The error message in the context is consumed and must be freed using
|
|
||||||
.Fn krb5_free_error_string
|
|
||||||
by the caller.
|
|
||||||
See also
|
|
||||||
.Fn krb5_get_error_message ,
|
|
||||||
what is usually less verbose to use.
|
|
||||||
.Pp
|
|
||||||
.Fn krb5_have_error_string
|
|
||||||
returns
|
|
||||||
.Dv TRUE
|
|
||||||
if there is a verbose error message in the
|
|
||||||
.Fa context .
|
|
||||||
.Pp
|
|
||||||
.Fn krb5_get_error_message
|
|
||||||
fetches the error string from the context, or if there
|
|
||||||
is no customized error string in
|
|
||||||
.Fa context ,
|
|
||||||
uses
|
|
||||||
.Fa code
|
|
||||||
to return a error string.
|
|
||||||
In either case, the error message in the context is consumed and must
|
|
||||||
be freed using
|
|
||||||
.Fn krb5_free_error_string
|
|
||||||
by the caller.
|
|
||||||
.Pp
|
|
||||||
.Fn krb5_set_warn_dest
|
|
||||||
and
|
|
||||||
.Fn krb5_get_warn_dest
|
|
||||||
sets and get the log context that is used by
|
|
||||||
.Fn krb5_warn
|
|
||||||
and friends. By using this the application can control where the
|
|
||||||
output should go. For example, this is imperative to inetd servers
|
|
||||||
where logging status and error message will end up on the output
|
|
||||||
stream to the client.
|
|
||||||
.Sh EXAMPLES
|
|
||||||
Below is a simple example how to report error messages from the
|
|
||||||
Kerberos library in an application.
|
|
||||||
.Bd -literal
|
|
||||||
#include <krb5.h>
|
|
||||||
|
|
||||||
krb5_error_code
|
|
||||||
function (krb5_context context)
|
|
||||||
{
|
|
||||||
krb5_error_code ret;
|
|
||||||
|
|
||||||
ret = krb5_function (context, arg1, arg2);
|
|
||||||
if (ret) {
|
|
||||||
char *s = krb5_get_error_message(context, ret);
|
|
||||||
if (s == NULL)
|
|
||||||
errx(1, "kerberos error: %d (and out of memory)", ret);
|
|
||||||
application_logger("krb5_function failed: %s", s);
|
|
||||||
krb5_free_error_string(context, s);
|
|
||||||
return ret;
|
|
||||||
}
|
|
||||||
return 0;
