enable remote access to -the netgraph subsystem. -It also exports a number of global variables and -functions, that allow other modules to easily use the netgraph system. -.Pp -If upon start up of the module the variable -.Va begemotNgControlNodeName -is not empty the module opens a netgraph socket and names that socket node. -If the variable is empty, the socket is created, as soon as the variable is -written with a non-empty name. -The socket can be closed by writing an empty -string to the variable. -The socket itself and its name are available in -.Va snmp_node -and -.Va snmp_nodename . -.Ss SENDING AND RECEIVING MESSAGES AND DATA -There are three functions for sending control message: -.Bl -tag -width ".It Fn ng_output_node" -.It Fn ng_output -sends a control message along the given -.Fa path . -.It Fn ng_output_node -sends a control message to the node with name -.Fa node -and -.It Fn ng_output_id -sends a control message to the node with node id -.Fa id . -.El -.Pp -Each of these functions takes the following arguments: -.Bl -tag -width ".It Fa cookie" -.It Fa cookie -is the node specific command cookie, -.It Fa opcode -is the node specific code for the operation to performa, -.It Fa arg -is a pointer to the message itself. -This message must start with a -.Vt struct ng_mesg . -.It Fa arglen -is the overall length of the message (header plus arguments). -.El -The functions return the message id that can be used to match incoming responses -or -1 if an error occurs. -.Pp -Another class of functions is used to send a control message and to wait for -a matching response. -Note, that this operation blocks the daemon, so use it -only if you are sure that the response will happen. -There is a maximum timeout -that is configurable in the MIB variable -.Va begemotNgTimeout . -Other messages arriving while the functions are waiting for the response are -queued and delivered on the next call to the module's idle function. -.Bl -tag -width ".It Fn ng_output_node" -.It Fn ng_dialog -sends a control message along the given -.Fa path -and waits for a matching response. -.It Fn ng_dialog_node -sends a control message to the node with name -.Fa node -and waits for a matching response. -.It Fn ng_dialog_id -sends a control message to the node with id -.Fa id -and waits for a matching response. -.El -.Pp -All three functions take the same arguments as the -.Fn ng_output* -functions. -The functions return the reponse message in a buffer allocated by -.Xr malloc 3 -or NULL in case of an error. -The maximum size of the response buffer can be -configured in the variable -.Va begemotNgResBufSiz . -.Pp -A data message can be send with the function -.Fn ng_send_data . -This function takes the name of the -.Va snmp_node Ns 's -hook through which to send the data, a pointer to the message buffer and -the size of the message. -It returns -1 if an error happens. -.Ss ASYNCHRONOUS CONTROL AND DATA MESSAGES -A module can register functions to asynchronuosly receive control and data -message. -.Pp -The function -.Fn ng_register_cookie -registers a control message receive function. -If a control message is -received, that is not consumed by the dialog functions, the list of registerred -control message receive functions is scanned. -If the cookie in the received -message is the same as the -.Fa cookie -argument to the -.Fn ng_register_cookie -call and the -.Fa id -argument to the -.Fn ng_register_cookie -call was either 0 or equals the node id which sent the control message, the -handler function -.Fa func -is called with a pointer to the received message, the hook on which the -message was received (or NULL if it was received not on a hook), the id -of the sender's node and the -.Fa uarg -argument of the registration call. -The handler function should not modify -the contents of the message, because more than one function may be registered -to the same cookie and node id. -.Pp -A control message registration can be undone by calling -.Fn ng_unregister_cookie -with the return value of the registration call. -If an error occures while registering, -.Fn ng_register_cookie -returns NULL. -.Pp -A module can call -.Fn ng_register_hook -to register a callback for data messages on one of the -.Va snmp_node Ns 's -hooks. -If a data message is received on that hook, the callback function -.Fa func -is called with the hook name, a pointer to the data message, the size of -the message and the argument -.Fa uarg -to the registration function. -The message should be treated as read-only. -A data message registration can be undone by calling -.Fn ng_unregister_hook -with the return value of the registration call. -If an error occures while registering, -.Fn ng_register_hook -returns NULL. -.Pp -The function -.Fn ng_unregister_module -removes all control and data registrations for that module. -.Ss FINDING NODES AND NODE CHARACTERISTICS -.Pp -The function -.Fn ng_node_id -returns the id of the node addressed by -.Fa path -or 0 if the node does not exists. -.Pp -The function -.Fn ng_node_id_node -returns the id of the node with name -.Fa node -or 0 if the node does not exist. -.Pp -The function -.Fn ng_node_node -retrieves the name of the node with id -.Fa id -and writes it to the buffer pointed to by -.Fa name . -This buffer should be at least -.Li NG_NODESIZ -bytes long. -The function returns the node id or 0 if the -node is not found -.Pp -The function -.Fn ng_node_type -retrieves the name of the node with id -.Fa id -and writes it to the buffer pointed to by -.Fa type . -This buffer should be at least -.Li NG_TYPESIZ -bytes long. -The function returns the node id or 0 if the -node is not found. -.Pp -The function -.Fn ng_peer_hook_id -writes the name of the peer hook of the hook -.Fa hook -on the node with -.Fa id -to the buffer pointed to by -.Fa peer_hook . -The buffer should be at least -.Li NG_HOOKSIZ -bytes long. -The function returns 0 if the node and the hook is found, -1 -otherwise. -The function skips intermediate tee nodes (see -.Xr ng_tee 4 ) . -.Pp -The function -.Fn ng_next_node_id -returns the node id of the peer node that is on the other side of hook -.Fa hook -of node -.Fa id . -If -.Fa type -is not NULL, the function checks, that the peer node's type is -.Fa type . -The function skips intermediate tee nodes (see -.Xr ng_tee 4 ) . -It returns the node id of the peer node or 0 if an error occurres or the -types do not match. -.Ss CHANGING THE GRAPH -A number of functions can be used to create or destroy nodes and hooks. -.Pp -The function -.Fn ng_mkpeer_id -creates a new node of type -.Fa type -whose hook -.Fa peerhook -will be connected to -.Fa hook -of node -.Fa id . -If -.Fa name -is not NULL the new node is named with this name. -The function returns -The node id of the new node or 0 if an error happens. -.Pp -The functions -.Fn ng_connect_node -and -.Fn ng_connect_id -make a new hook connecting -.Fa ourhook -of the modules socket node -.Va snmp_node -to -.Fa peerhook -of the node identified by id -.Fa id -or name -.Fa node . -The functions return 0 on success or -1 otherwise. -.Pp -The function -.Fn ng_connect2_id -connects hook -.Fa ourhook -of the node with id -.Fa id -to hook -.Fa peerhook -of the node with id -.Fa peer . -The functions return 0 on success or -1 otherwise. -The function -.Fn ng_connect2_tee_id does the same as -.Fn ng_connect2_id -except, that it puts an unnamed tee node between the two nodes. -.Pp -The function -.Fn ng_rmhook -removes hook -.Fa hook -on the module's -.Va snmp_node . -The function -.Fn ng_rmhook_id -removes hook -.Fa hook -on the node with id -.Fa id . -The function -.Fn ng_rmhook_tee_id -additionally shuts down all tee nodes between the node and the first non-tee -peer. -.Pp -The function -.Fn ng_shutdown_id -destroys the given node. -.Sh FILES -.Bl -tag -width "XXXXXXXXX" -.It Pa /usr/share/bsnmp/defs/netgraph_tree.def -The description of the MIB tree
