update_alias( ) Function
The update_alias( ) function copies from the structure referenced by the alias
pointer parameter to the alias table entry specified by the index parameter.
The Neuron 3120 Chip with version 4 firmware does not support aliasing.
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.
See the ISO/IEC 14908 (ANSI/EIA/CEA-709.1)
Control Network Specification for
a description of the data structure.
Syntax
#include
void update_alias (const alias_struct * alias , int index );
Example
#include
alias_struct alias_copy;
unsigned int index;
void f(void)
{
alias_copy = *(access_alias(index));
// Modify the alias_copy here as necessary
update_alias(&alias_copy, index);
}
update_clone_domain( ) Function
The update_clone_domain( ) function copies from the structure referenced by the
domain pointer parameter to the domain table entry specified by the index
parameter.
This function differs from update_domain( ) in that it is only used for a cloned
device. A cloned device is a device that does not have a unique
