a description of the data structure.

Syntax

#include <access.h>

void update_config_data (const config_data_struct *

);

Example

#include <access.h>

config_data_struct config_data_copy;

void f(void)

{

config_data_copy = config_data;

// Modify the config_data_copy as necessary

update_config_data(&config_data_copy);

}

update_domain( ) Function

The update_domain( ) function copies from the structure referenced by the

domain

pointer parameter to the domain table entry specified by the

index

parameter.

Important: This function has a mechanism that ensures that a reset or power

cycle during an EEPROM modification does not cause the device to go

unconfigured. This mechanism uses the error log to serve as a semaphore. Thus,

the error log is written to on every call to this function, even if the net effect of

the function is to not modify or write to the configuration data at all (because the

new contents match the old). Applications must minimize calls to this function to

ensure that the maximum number of supported writes for EEPROM is not

exceeded over the lifetime of the application.
