GSS_DISPLAY_STATUS(3)						Programmer's Manual					     GSS_DISPLAY_STATUS(3)

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); } while (message_context != 0);
PARAMETERS
minor_status Mechanism specific status code. status_value Status value to be converted 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 sta- tus_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.
