Using tcp

The tcp package is loaded by

     :- use_module(library(tcp)).

This package relies on the flag fileerrors being set, which is the default. See fileerrors/0 (ref-iou-sfh-sem) and prolog_flag/3 (ref-lps-ove) for more about this flag. If fileerrors is not set, the behavior of this package is unpredictable. While we're on the subject of flags, it is also probably a good idea to set the flag syntax_errors to error (see ref-ere-err-syn). In summary, we recommend that the commands


be issued before connections are established.
