The usual way is to do:
signal(SIGPIPE, SIG_IGN);
which says to ignore that signal rather than deliver it. This is a
stateful setting, which remains set until the process ends or you
change it. This is a portable construct (though most other uses
of signal() are not portable).
The return value can be used to re-establish the former SIGPIPE
handler if you want; or it can just be thrown away if you're doing
this in mainline (rather than library) code and you know you don't
ever want to restore the default or former setting.
