    NAME

    gss_display_status
    
     - Convert a GSS-API status code to text
    
    
    
     
    

    SYNOPSIS

       #include <gssapi/gssapi.h>
    OM_uint32 Fo gss_display_status Fa OM_uint32 *minor_status Fa OM_uint32 status_value Fa int status_type Fa const gss_OID mech_type Fa OM_uint32 *message_context Fa gss_buffer_t status_string Fc  

    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 Fa message_context parameter is used by gss_display_status ();
    to store state information about which error messages have already been extracted from a given Fa status_value ; Fa 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 Fa message_context parameter contains all state information required by gss_display_status ();
    in order to extract further messages from the Fa 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
    Fa status_value is a GSS status code
    GSS_C_MECH_CODE
    Fa 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 Fa status_value , Fa status_type , Fa mech_type , and Fa message_context parameters.
    status_string
    Textual interpretation of the Fa 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
