Return Value:
Description: Posts error messages to the output queue. Returns the next error number followed by its corre-

and the next error message is made available. When all errors have been read, the query returns
0,”No error”. If more errors are accumulated than the queue can hold, it will overflow. The oldest errors
stay in the queue but the most recent errors are discarded. The last error in the queue will be
-350,”Too many errors.” Error messages are defined in Table B-6.
