 @deftypevr Macro int SIGPIPE
-If you use pipes or FIFO special files, you have to design your
-application so that one process opens the pipe for reading before
-another starts writing.  If the reading process never starts, or
-terminates unexpectedly, a write to the pipe or FIFO causes the writing
-process to receive a @code{SIGPIPE} signal.

 Pipes and FIFO special files are discussed in more detail in @ref{Pipes
 and FIFOs}.

+@code{SIGPIPE} also occurs when you try to output to a socket that isn't
+connected.  @xref{Sending Data}.
