It almost "shadows" the ending .El request of a list, which seems to have caused mdoc buglets in some gss_*.3 manpages. MFC after: 3 days

.Sh DESCRIPTION
|
|
Allows an application to obtain a textual representation of a GSS-API
|
|
status code,
|
|
for display to the user or for logging purposes.
|
|
Since some status values may indicate multiple conditions,
|
|
applications may need to call
|
|
.Fn gss_display_status
|
|
multiple times,
|
|
each call generating a single text string.
|
|
The
|
|
.Fa message_context
|
|
parameter is used by
|
|
.Fn gss_display_status
|
|
to store state information about which error messages have already
|
|
been extracted from a given
|
|
.Fa status_value ;
|
|
.Fa message_context
|
|
must be initialized to zero by the application prior to the first call,
|
|
and
|
|
.Fn gss_display_status
|
|
will return a non-zero value in this parameter if there are further
|
|
messages to extract.
|
|
.Pp
|
|
The
|
|
.Fa message_context
|
|
parameter contains all state information required by
|
|
.Fn gss_display_status
|
|
in order to extract further messages from the
|
|
.Fa status_value ;
|
|
even when a non-zero value is returned in this parameter,
|
|
the application is not required to call
|
|
.Fn gss_display_status
|
|
again unless subsequent messages are desired.
|
|
The following code extracts all messages from a given status code and prints them to stderr:
|
|
.Bd -literal
|
|
OM_uint32 message_context;
|
|
OM_uint32 status_code;
|
|
OM_uint32 maj_status;
|
|
OM_uint32 min_status;
|
|
gss_buffer_desc status_string;
|
|
|
|
...
|
|
|
|
message_context = 0;
|
|
|
|
do {
|
|
|
|
maj_status = gss_display_status (
|
|
&min_status,
|
|
status_code,
|
|
GSS_C_GSS_CODE,
|
|
GSS_C_NO_OID,
|
|
&message_context,
|
|
&status_string)
|
|
|
|
fprintf(stderr,
|
|
"%.*s\\n",
|
|
(int)status_string.length,
|
|
(char *)status_string.value);
|
|
|
|
gss_release_buffer(&min_status, &status_string);
|
|
|
|
} while (message_context != 0);

|
to obtain the system default.
|
|
.It message_context
|
|
Should be initialized to zero by the application prior to the first
|
|
call.
|
|
On return from
|
|
.Fn gss_display_status ,
|
|
a non-zero status_value parameter indicates that additional messages
|
|
may be extracted from the status code via subsequent calls to
|
|
.Fn gss_display_status ,
|
|
passing the same
|
|
.Fa status_value ,
|
|
.Fa status_type ,
|
|
.Fa mech_type ,
|
|
and
|
|
.Fa message_context
|
|
parameters.
|
|
.It status_string
|
|
Textual interpretation of the
|
|
.Fa status_value .
|
|
Storage associated with this parameter must be freed by the
