* The @c node is initialized for high login mode. The following steps are performed: | |||||
* 1. The sports node group directory is searched for a matching set of service parameters. | |||||
* 2. If a matching set is not found, a node group directory entry is allocated. | |||||
* 3. If less than the @c hlm_group_size number of remote node group objects is present in the | |||||
* node group directory, a new remote node group object is allocated and added to the list. | |||||
* 4. A remote node group object is selected, and the node is attached to the node group. | |||||
* | |||||
* @param node Pointer to the node. | |||||
* | |||||
* @return Returns 0 on success, or a negative error value on failure. | |||||
