The gss_display_name() function allows an application to obtain a textual representation of an opaque internal-form name for display purposes.

If input_name denotes an anonymous principal, the GSS-API returns the gss_OID value GSS_C_NT_ANONYMOUS as the output_name_type, and a textual name that is syntactically distinct from all valid supported printable names in output_name_buffer.

If input_name was created by a call to gss_import_name(3GSS), specifying GSS_C_NO_OID as the name-type, the GSS-API returns GSS_C_NO_OID by means of the output_name_type parameter.

The parameter descriptions for gss_display_name() follow:

minor_status

Mechanism-specific status code.

input_name

Name in internal form.

output_name_buffer

Buffer to receive textual name string. The application must free storage associated with this name after use with a call to gss_release_buffer(3GSS).

output_name_type

The type of the returned name. The returned gss_OID will be a pointer into static storage and should be treated as read-only by the caller. In particular, the application should not attempt to free it. Specify NULL if this parameter is not required.

The gss_display_name() function may return the following status codes:

GSS_S_COMPLETE

Successful completion.

GSS_S_BAD_NAME

The input_name was ill-formed.

GSS_S_FAILURE

The underlying mechanism detected an error for which no specific GSS status code is defined. The mechanism-specific status code reported by means of the minor_status parameter details the error condition.
