Displaying Status Codes

The function gss_display_status() translates GSS-API status codes into text format. This format allows the codes to be displayed to a user or put in a text log. gss_display_status() only displays one status code at a time, and some functions can return multiple status conditions. Accordingly, gss_display_status() should be called as part of a loop. When gss_display_status() indicates a non-zero status code, another status code is available for the function to fetch.

Example B–1 Displaying Status Codes with gss_display_status()

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);
