Used to wait synchronously on an event mask.

Parameters

mgmt_event_mask	A mask of relevant events to wait on.
raised_event	a pointer on a uint32_t to get which event from the mask generated the event. Can be NULL if the caller is not interested in that information.
iface	a pointer on a place holder for the iface on which the event has originated from. This is valid if only the event mask has bit NET_MGMT_IFACE_BIT set relevantly, depending on events the caller wants to listen to.
info	a valid pointer if user wants to get the information the event might bring along. NULL otherwise.
info_length	tells how long the info memory area is. Only valid if the info is not NULL.
timeout	A timeout delay. K_FOREVER can be used to wait indefinitely.

Returns: 0 on success, a negative error code otherwise. -ETIMEDOUT will be specifically returned if the timeout kick-in instead of an actual event.

◆ net_mgmt_event_wait_on_iface()

int net_mgmt_event_wait_on_iface	(	struct net_if *	iface,

	)

#include <zephyr/net/net_mgmt.h>

Used to wait synchronously on an event mask for a specific iface.

Parameters

iface	a pointer on a valid network interface to listen event to
mgmt_event_mask	A mask of relevant events to wait on. Listened to events should be relevant to iface events and thus have the bit NET_MGMT_IFACE_BIT set.
raised_event	a pointer on a uint32_t to get which event from the mask generated the event. Can be NULL if the caller is not interested in that information.
info	a valid pointer if user wants to get the information the event might bring along. NULL otherwise.
info_length	tells how long the info memory area is. Only valid if the info is not NULL.
timeout	A timeout delay. K_FOREVER can be used to wait indefinitely.

Returns: 0 on success, a negative error code otherwise. -ETIMEDOUT will be specifically returned if the timeout kick-in instead of an actual event.

◆ net_mgmt_init_event_callback()
