resp_send( ) Built-in Function
The resp_send( ) built-in function sends a response using the resp_out object. See
Chapter 6, How Devices Communicate Using Application Messages, of the
Neuron C Programmer's Guide for more information.
Syntax
void resp_send (void);
Example
# define DATA_REQUEST 0
# define OK 1
when (msg_arrives(DATA_REQUEST)))
{
unsigned x, y;
x = msg_in.data[0];
y = get_response(x);
resp_out.code = OK;
// msg_in no longer available
resp_out.data[0] = y;
resp_send();
}
retrieve_status( ) Function
The retrieve_status( ) function returns diagnostic status information to the
Neuron C application. This information is also available to a network tool over
the network, through the Query Status network diagnostics message. The
status_struct structure, defined in <status.h>, is shown below.
Syntax
#include <status.h>
void retrieve_status (status_struct * p );
typedef struct status_struct {
unsigned long status_xmit_errors;
unsigned long status_transaction_timeouts;
