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.
