AR_GET_LATEST  

void ar_get_latest (CEI_INT16 board, CEI_INT16 channel, CEI_UINT16 
label, CEI_INT32 *data, CEI_CHAR *seqno); 

This routine retrieves ARINC data when “Dedicated” data storage mode is 
in effect (see AR_SET_STORAGE_MODE).  It returns the most recently 
received data for a selected label and channel.  It also returns an eight-bit 
sequence number that indicates the number of 32-bit ARINC words 
received for that combination of label and channel.   

For the CEI-100/200 and CEI-520/520A/620/820/820TX, if no data has 

been received, this routine returns a data word with zero in all bits 

except for the label field, which has the requested label value.  Because 

the sequence number is stored in the label field on the hardware, the 

label is re-inserted by this routine after the sequence number has been 

extracted from the hardware data. The CEI-220/420/420A returns a data 

word containing all zeros if no labels have been received. 

If you are using the CEI-520/520A/620/820/820TX enhanced API, the 
“DEDICATED’ storage mode is always operational, and this function is 
enhanced as follows: 

 

The entry point, AR_GET_LATEST, is used to return the latest value 
for a label/channel.  This function gets data from the “DEDICATED” 
storage mode Snap Shot buffer 'SnapRBuf'.  It returns the most 
recently received data for a selected label and channel.  It also returns 
the eight-bit sequence number that indicates the number of ARINC 
words received for that combination of label and channel. 

 

If the label requested is label 256 (an ARINC label that does not exist) 
or the value “ARU_ALL_LABELS”, this function returns 

all

 256 

ARINC labels and sequence numbers for the specified channel, in 
sequence, in successive “data” and “seqno” array elements.  This 
function assumes that the caller has allocated at least 256*4 bytes for 
“data” and at least 256 bytes for “seqno” when being used in this 
mode.
