- hdx(+StreamPair, +Term, -Codes, +TimeOut) is semidet
- hdx(+In, -Codes, +TimeOut) is semidet
- hdx(+Out, +Term) is semidet
- Performs a single half-duplex stream interaction with StreamPair.
Flushes Term to the output stream. Reads pending Codes from the
input stream within TimeOut seconds. Succeeds when a write-read
cycle completes without timing out; fails on time-out expiry.
Filling a stream buffer blocks the calling thread if there is no
input ready. Pending read operations also block for the same reason.
Hence the wait_for_input/3 must precede them.
|StreamPair||- connection from client to server, a
closely-associated input and output stream pairing used for
|Term||- to write and flush.|
|Codes||- waited for and extracted from the pending input stream.|
|TimeOut||- in seconds.|
