This function is similar to krb5_unparse_name() , but allows the use of an existing buffer for the result. If size is not NULL, then *name must be either NULL or an existing buffer of at least size *size. The buffer will be allocated or resized if necessary, with the new pointer stored into *name. Whether or not the buffer is resized, the necessary space for the result, including null terminator, will be stored into *size.

If size is NULL, this function behaves exactly as krb5_unparse_name() .
