GSS_DISPLAY_STATUS(3) FreeBSD Library Functions Manual (prm)
NAME
gss_display_status - Convert a GSS-API status code to text
SYNOPSIS
#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
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 zero 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,
"%.*s\n",
(int)status_string.length,
(char *)status_string.value);
gss_release_buffer(&min_status, &status_string);
status_type
GSS_C_GSS_CODE status_value is a GSS status code
GSS_C_MECH_CODE status_value is a mechanism status code
mech_type Underlying mechanism (used to interpret a minor status
value). Supply GSS_C_NO_OID to obtain the system default.
message_context
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.
status_string
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().
RETURN VALUES
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.
