Since some status values may indicate multiple conditions, applications may need to call .Fn gss_display_status multiple times, each call generating a single text string. The .Fa message_context parameter is used by .Fn 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 .Fn gss_display_status will return a non-zero value in this parameter if there are further messages to extract. .Pp The .Fa message_context parameter contains all state information required by .Fn 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 .Fn 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: .Bd -literal 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); .Ed .Sh PARAMETERS .Bl -tag -width ".It minor_status" .It minor_status Mechanism specific status code. .It status_value Status value to be converted .It status_type .Bl -tag -width ".It GSS_C_MECH_CODE" .It GSS_C_GSS_CODE .Fa status_value is a GSS status code .It GSS_C_MECH_CODE .Fa status_value is a mechanism status code .El .It mech_type Underlying mechanism (used to interpret a minor status value).

On return from .Fn gss_display_status , a non-zero status_value parameter indicates that additional messages may be extracted from the status code via subsequent calls to .Fn gss_display_status , passing the same .Fa status_value , .Fa status_type , .Fa mech_type , and .Fa message_context parameters. .It status_string Textual interpretation of the .Fa status_value .
