NAME
gss_display_status - API function
SYNOPSIS
#include <gss.h>
OM_uint32 gss_display_status(OM_uint32 * minor_status, OM_uint32
status_value, int status_type, const gss_OID mech_type, OM_uint32 *
message_context, gss_buffer_t status_string);
ARGUMENTS
OM_uint32 * minor_status
(integer, modify) Mechanism specific status code.
OM_uint32 status_value
(Integer, read) Status value to be converted.
int status_type
(Integer, read) GSS_C_GSS_CODE - status_value is a
GSS status code. GSS_C_MECH_CODE - status_value is a
mechanism
status code.
const gss_OID mech_type
(Object ID, read, optional) Underlying mechanism (used
to interpret a minor status value). Supply GSS_C_NO_OID
to obtain
the system default.
OM_uint32 * message_context
(Integer, read/modify) Should be initialized to
zero by the application prior to the first call. On
return from
gss_display_status(), a non-zero status_value parameter
indicates
that additional messages may be extracted from the status
code
via subsequent calls to gss_display_status(), passing the
same
status_value, status_type, mech_type, and message_context
parameters.
gss_buffer_t status_string
(buffer, character string, modify) Textual
interpretation of the status_value. Storage associated
with this
parameter must be freed by the application after use with
a call
to gss_release_buffer().
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 gss_display_status multiple times, each call generating a
single text string. The message_context parameter is used by
gss_display_status to store state information about which error
messages have already been extracted from a given status_value;
message_context must be initialized to 0 by the application prior to
the first call, and gss_display_status will return a non-zero value in
this parameter if there are further messages to extract.
The message_context parameter contains all state information required
by gss_display_status in order to extract further messages from the
status_value; even when a non-zero value is returned in this parameter,
the application is not required to call 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:
--------------------------------------------------- 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,
"%.*s0,
(int)status_string.length,
(char *)status_string.value);
gss_release_buffer(&min_status, &status_string);
} while (message_context != 0);
---------------------------------------------------
RETURN VALUE
‘GSS_S_COMPLETE‘: Successful completion.
‘GSS_S_BAD_MECH‘: Indicates that translation in accordance with an
unsupported mechanism type was requested.
‘GSS_S_BAD_STATUS‘: The status value was not recognized, or the status
type was neither GSS_C_GSS_CODE nor GSS_C_MECH_CODE.
