ccurDDC1553_outGetNextMessageAddress()

void * ccurDDC1553_outGetNextMessageAddress

(

)

Return the address of the next available DDC 1553 message buffer in the output queue.
The caller must fill the buffer with the DDC 1553 data and then call ccurDDC1553_outputQPut to place the element int the queue.

Returns

The address of the next available message buffer. NULL if the queue is full . The queue can fill up if the consumer processes data slower that the producer places element in the queue.
