Please note that there is another method of trapping signals, namely "intercept()"

(q.v.). However, since "signal()" and "intercept()" are mutually incompatible, calls to both of them must not appear in the same program. The link-loader will preven the creation of an executable program in which both are called by aborting with an "entry name clash" error for "_sigint".
