NAME
net_instance_register - register a set of instances to occur with IP instance events SYNOPSIS
#include <sys/neti.h> int net_instance_register(net_instance_t *instances); INTERFACE LEVEL
Solaris DDI specific (Solaris DDI). PARAMETERS
instances must be a pointer returned by net_instance_alloc(9F). DESCRIPTION
The net_instance_register() function attempts to record the set of functions passed by instances that are to be called when an event related to IP instance maintenance occurs. RETURN VALUES
If the net_instance_register() function succeeds, DDI_SUCCESS is returned. Otherwise, DDI_FAILURE is returned to indicate failure due to the name in the instance already being present. CONTEXT
The net_instance_register() function may be called from user or kernel context. ATTRIBUTES

NAME
net_instance_notify_register, net_instance_notify_unregister - add/delete a function to be called for changes to an instance SYNOPSIS
#include <sys/hook.h> #include <sys/neti.h> int net_instance_notify_register(net id_t net_id, hook_notify_fn_t *callback, void *arg); int net_instance_notify_unregister(net id_t net_id, hook_notify_fn_t *callback); typedef int (* hook_notify_fn_t)(hook_notify_cmd_t command, void *arg, const char *name1, const char *name2, const char *name3); INTERFACE LEVEL
Solaris DDI specific (Solaris DDI). PARAMETERS
netid value from either callback registered with net_instance_register() or net_zoneidtonetid(). callback function to call when a change occurs. arg pointer to pass into the callback() function when a change occurs. DESCRIPTION
The net_instance_notify_register() function registers a function represented by the pointer callback to be called when there is a new instance added or removed from the given network instance (represented by netid.) The net_instance_notify_unregister() function indicates that there is no longer any desire to receive notification of changes to the instance through function calls to the specified callback. Multiple callback functions may be registered through this interface. The same set of parameters is passed to each callback function. The memory referenced through the pointers passed to the callback should be treated as pointing to read-only memory. Changing this data is strictly prohibited. The function that is called must not block any other events. The arguments passed through to the callback are as follows (the command is either HN_REGISTER or HN_UNREGISTER): name1 is the netid represented as a string. name2 is NULL. name3 is the name of the instance being added/removed RETURN VALUES
If these functions succeed, 0 is returned. Otherwise, the following error is returned: EEXIST the given callback function is already registered. CONTEXT
These functions may be called from user or kernel context. ATTRIBUTES
