gss_display_status - API function


#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);


(integer, modify) Mechanism specific status code.
(Integer, read) Status value to be converted.
(Integer, read) GSS_C_GSS_CODE - status_value is a
GSS status code. GSS_C_MECH_CODE - status_value is a mechanism
status code.
(Object ID, read, optional) Underlying mechanism (used
to interpret a minor status value). Supply GSS_C_NO_OID to obtain
the system default.
(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
(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().


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 (


(char *)status_string.value);

gss_release_buffer(&min_status, &status_string);

} while (message_context != 0); ---------------------------------------------------


`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.
