Detailed Description

Nut/Nut configuration structure.

Define Documentation

#define CONFNET_EE_OFFSET   64

Non-volatile memory location.

Offset into non-volatile memory, where Nut/Net stores the network configuration. The default may be overridden by the Configurator.

Referenced by NutNetLoadConfig(), and NutNetSaveConfig().

#define CONFNET_MAX_IF   1

Typedef Documentation

typedef struct _CONFNET CONFNET

Function Documentation

int NutNetLoadConfig

(

const char *

name

)

Load network configuration from non-volatile memory.

If no configuration is available in EEPROM, all configuration parameters are cleared to zero. Except the MAC address, which is set to the locally administered address 02-00-00-00-00-00.

Parameters:

name	Name of the device.

Returns:

0 if configuration has been read. Otherwise the return value is -1.

int NutNetSaveConfig

(

void

)

Save network configuration in non-volatile memory.

Returns:

0 if OK, -1 on failures.

Variable Documentation

CONFNET confnet

Global network configuration structure.

Contains the current network configuration. Nut/Net will load this structure from non-volatile memory during initialization.

Examples:

editconf/editconf.c, ftpd/ftpserv.c, httpd/httpserv.c, httpd_simple/httpd_simple.c, httpd_upnp/httpserv.c, inetq/inetq.c, logtime/logtime.c, pingnet/pingnet.c, and tcps/tcps.c.
