Function Documentation

ccurRS232_outGetNextMessageAddress()

void * ccurRS232_outGetNextMessageAddress

(

)

Return the address of the next available RS232 message buffer in the output queue.
The caller must fill the buffer with the RS232 data and then call ccurFADX_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.
