GSS_DISPLAY_STATUS(3GSS) Generic Security Services API Library Functions
gss_display_status - convert a GSS-API status code to text
cc [ flag... ] file... -lgss [ library... ]
#include <gssapi/gssapi.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);
The gss_display_status() function enables an application to obtain a
textual representation of a GSS-API status code for display to the
user or for logging purposes. Because some status values may
indicate multiple conditions, applications may need to call
gss_display_status() multiple times, with each call generating a
single text string.
The message_context parameter is used by gss_acquire_cred() to store
state information on error messages that are extracted from a given
status_value. The message_context parameter 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() to extract further messages from the
status_value. If 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 parameter descriptions for gss_display_status() follow:
minor_status
Status code returned by the underlying mechanism.
status_value
Status value to be converted.
status_type
If the value is GSS_C_GSS_CODE, status_value is a
GSS-API status code. If the value is
GSS_C_MECH_CODE, then status_value is a mechanism
status code.
mech_type
Underlying mechanism that is used to interpret a
minor status value. Supply GSS_C_NO_OID to obtain
the system default.
message_context
Should be initialized to zero 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 by means of subsequent calls to
gss_display_status(), passing the same
status_value, status_type, mech_type, and
message_context parameters.
status_string
Textual representation of the status_value.
Storage associated with this parameter must be
freed by the application after use with a call to
gss_release_buffer(3GSS).
The gss_display_status() function may return the following status
codes:
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.
GSS_S_FAILURE
The underlying mechanism detected an error for
which no specific GSS status code is defined.
The mechanism-specific status code reported by
means of the minor_status parameter details the
error condition.

NAME
gss_display_status - convert a GSS-API status code to text
SYNOPSIS
cc [ flag... ] file... -lgss [ library... ]
#include <gssapi/gssapi.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);
DESCRIPTION
The gss_display_status() function enables an application to obtain a
textual representation of a GSS-API status code for display to the
user or for logging purposes. Because some status values may
indicate multiple conditions, applications may need to call
gss_display_status() multiple times, with each call generating a

The message_context parameter is used by gss_acquire_cred() to store
state information on error messages that are extracted from a given
status_value. The message_context parameter 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() to extract further messages from the
status_value. If 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.
PARAMETERS
The parameter descriptions for gss_display_status() follow:
minor_status
Status code returned by the underlying mechanism.
status_value
Status value to be converted.
status_type
If the value is GSS_C_GSS_CODE, status_value is a
GSS-API status code. If the value is
GSS_C_MECH_CODE, then status_value is a mechanism
status code.
mech_type
Underlying mechanism that is used to interpret a
minor status value. Supply GSS_C_NO_OID to obtain
the system default.
message_context
Should be initialized to zero 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 by means of subsequent calls to
gss_display_status(), passing the same
status_value, status_type, mech_type, and
message_context parameters.
status_string
Textual representation of the status_value.
Storage associated with this parameter must be
freed by the application after use with a call to
gss_release_buffer(3GSS).
ERRORS
The gss_display_status() function may return the following status
codes:
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.
GSS_S_FAILURE
The underlying mechanism detected an error for
which no specific GSS status code is defined.
The mechanism-specific status code reported by
means of the minor_status parameter details the
error condition.
