3.141.1 VCB Structure
typedef struct query_nn_topology_node
{
AP_UINT16 opcode; /* verb operation code */
unsigned char reserv2; /* reserved */
unsigned char format; /* reserved */
AP_UINT16 primary_rc; /* primary return code */
AP_UINT32 secondary_rc; /* secondary return code */
unsigned char *buf_ptr; /* pointer to buffer */
AP_UINT32 buf_size; /* buffer size */
AP_UINT32 total_buf_size; /* total buffer size required */
AP_UINT16 num_entries; /* number of entries */
AP_UINT16 total_num_entries; /* total number of entries */
unsigned char list_options; /* listing options */
unsigned char reserv3; /* reserved */
unsigned char node_name[17]; /* network qualified node name */
unsigned char node_type; /* node type */
AP_UINT32 frsn; /* flow reduction sequence number */
} QUERY_NN_TOPOLOGY_NODE;
If the frsn field is set to a non-zero value then only node entries with FRSNs equal to or greater than the one
specified will be returned. If it is set to zero then all node entries are returned.
typedef struct nn_topology_node_summary
{
