Macro Definition Documentation

NET_SOCKET_SERVICE_SYNC_DEFINE

#define NET_SOCKET_SERVICE_SYNC_DEFINE	(		name,
			cb,
			count )

#include <zephyr/net/socket_service.h>

Value:

        __z_net_socket_service_define(name, cb, count)

Statically define a network socket service.

The user callback is called synchronously for this service meaning that the service API will wait until the user callback returns before continuing with next socket service.

The socket service can be accessed outside the module where it is defined using:

extern struct net_socket_service_desc <name>; 

Note

This macro cannot be used together with a static keyword. If such a use-case is desired, use NET_SOCKET_SERVICE_SYNC_DEFINE_STATIC instead.

Parameters

name	Name of the service.
cb	Callback function that is called for socket activity.
count	How many pollable sockets is needed for this service.

NET_SOCKET_SERVICE_SYNC_DEFINE_STATIC

#define NET_SOCKET_SERVICE_SYNC_DEFINE_STATIC	(		name,
			cb,
			count )

#include <zephyr/net/socket_service.h>

Value:

        __z_net_socket_service_define(name, cb, count, static)

Statically define a network socket service in a private (static) scope.

The user callback is called synchronously for this service meaning that the service API will wait until the user callback returns before continuing with next socket service.

Parameters

name	Name of the service.
cb	Callback function that is called for socket activity.
count	How many pollable sockets is needed for this service.

Typedef Documentation

net_socket_service_cb_t

typedef void(* net_socket_service_cb_t) (const struct net_socket_service_desc *svc, void *user_data)

#include <zephyr/net/socket_service.h>

Callback used while iterating over socket services.

Parameters

svc	Pointer to current socket service.
user_data	A valid pointer to user data or NULL

net_socket_service_handler_t

typedef void(* net_socket_service_handler_t) (struct net_socket_service_event *pev)

#include <zephyr/net/socket_service.h>

The signature for a net socket service handler function.

The function will be invoked by the socket service.

Parameters

pev	the socket service event that provided the handler.

Function Documentation

net_socket_service_foreach()

void net_socket_service_foreach	(	net_socket_service_cb_t	cb,
		void *	user_data )

#include <zephyr/net/socket_service.h>

Go through all the socket services and call callback for each service.

Parameters

cb	User-supplied callback function to call
user_data	User specified data

net_socket_service_register()

int net_socket_service_register	(	const struct net_socket_service_desc *	service,
		struct zsock_pollfd *	fds,
		int	len,
		void *	user_data )

#include <zephyr/net/socket_service.h>

Register pollable sockets.

Parameters

service	Pointer to a service description.
fds	Socket array to poll.
len	Length of the socket array.
user_data	User specific data.

Return values

0	No error
-ENOENT	Service is not found.
-ENINVAL	Invalid parameter.

net_socket_service_unregister()

static int net_socket_service_unregister ( const struct net_socket_service_desc * service )

inlinestatic

#include <zephyr/net/socket_service.h>

Unregister pollable sockets.

Parameters

service

Pointer to a service description.

Return values

0	No error
-ENOENT	Service is not found.
-ENINVAL	Invalid parameter.
