The handle argument is iterator handle obtained by cpg_iteration_inital- ize(3) function. description is pointer to structure with following definition: struct cpg_iteration_description_t { struct cpg_name group; uint32_t nodeid; uint32_t pid; }; where group is name of group, nodeid is ID of connected node and pid is pid of connected process. If iteration was initialized with CPG_ITERATION_NAME_ONLY iteration type, both nodeid and pid are 0.RETURN VALUEThis call returns the CS_OK value if successful. If there are no more items to iterate, CS_NO_SECTION error code is returned.SEE ALSOcpg_iteration_initialize(3), cpg_overview(8) CS_ERR_TRY_AGAIN Resource temporarily unavailable CS_ERR_INVALID_PARAM Invalid argument CS_ERR_ACCESS Permission denied CS_ERR_LIBRARY The connection failed CS_ERR_INTERRUPT System call inturrupted by a signal CS_ERR_NOT_SUPPORTED The requested protocol/functuality not supported CS_ERR_MESSAGE_ERROR Incorrect auth message received CS_ERR_NO_MEMORY Not enough memory to completed the requested task corosync Man Page 05/03/2012 CPG_ITERATION_NEXT(3)
