+/**
+ * frsh_group_change_mode_sync()
+ *
+ * This function performs a set of negotiation operations which can
+ * include: adding new contracts (neg), modifying existing vres (reneg)
+ * or cancelling existing vres (cancel).
+ *
+ * If one of the group operations has a NULL value, unless it causes an
+ * inconsistency the system will suppose that no operation of that
+ * type (neg, reneg or cancel) should be done.
+ *
+ * The virtual resources resulting from negotiations of new contracts are
+ * returned in the parameter 'new_vres' which must be provided by the user.
+ *
+ * If the on-line admission test is enabled, FRSH analizes the
+ * schedulability of the context that would result in the new
+ * contract situation with removed, changed and added contracts.
+ *
+ * A successful return code will mean that all contracts have been
+ * accepted and all required operations (creation, cancellation or
+ * update of vres) have been carried out to reach the new running
+ * context.
+ *
+ * If any of the contracts is not accepted a corresponding error shall be
+ * returned and no changes will be made to the previously running context.
+ *
+ * This call is a synchronous, potentially blocking operation. It
+ * returns when the system has rejected the contracts or accepted
+ * and made them effective.
