NET_HOSTNAME_MAX_LEN

#define NET_HOSTNAME_MAX_LEN

#include <zephyr/net/hostname.h>

Value:

        (sizeof(CONFIG_NET_HOSTNAME) - 1 +                                                         \
         (IS_ENABLED(CONFIG_NET_HOSTNAME_UNIQUE) ? sizeof("0011223344556677") - 1 : 0))

Maximum hostname length.

Function Documentation

net_hostname_get()

static const char * net_hostname_get ( void  )

inlinestatic

#include <zephyr/net/hostname.h>

Get the device hostname.

Return pointer to device hostname.

Returns

Pointer to hostname or NULL if not set.

net_hostname_init()

static void net_hostname_init ( void  )

inlinestatic

#include <zephyr/net/hostname.h>

Initialize and set the device hostname.

net_hostname_set()

static int net_hostname_set ( char *  host, size_t  len  )

inlinestatic

#include <zephyr/net/hostname.h>

Set the device hostname.

Parameters

host	new hostname as char array.
len	Length of the hostname array.

Returns

0 if ok, <0 on error

net_hostname_set_postfix()

static int net_hostname_set_postfix ( const uint8_t *  hostname_postfix, int  postfix_len  )

inlinestatic

#include <zephyr/net/hostname.h>

Set the device hostname postfix.

Set the device hostname to some value. This is only used if CONFIG_NET_HOSTNAME_UNIQUE is set.

Parameters

hostname_postfix	Usually link address. The function will convert this to a string.
postfix_len	Length of the hostname_postfix array.

Returns

0 if ok, <0 if error
