On Unix-like systems, when a write
to <a href="/pkg/os/#pkg-variables"><code>os.Stdout</code>
or <code>os.Stderr</code></a> (more precisely, an <code>os.File</code>
opened for file descriptor 1 or 2) fails due to a broken pipe error,
the program will raise a <code>SIGPIPE</code> signal.
By default this will cause the program to exit; this may be changed by
calling the
<a href="/pkg/os/signal"><code>os/signal</code></a>
<a href="/pkg/os/signal/#Notify"><code>Notify</code></a> function
for <code>syscall.SIGPIPE</code>.
A write to a broken pipe on a file descriptor other 1 or 2 will simply
return <code>syscall.EPIPE</code> (possibly wrapped in
<a href="/pkg/os#PathError"><code>os.PathError</code></a>
and/or <a href="/pkg/os#SyscallError"><code>os.SyscallError</code></a>)
to the caller.
The old behavior of raising an uncatchable <code>SIGPIPE</code> signal
after 10 consecutive writes to a broken pipe no longer occurs.
