-      In a Go library built with <code>-buildmode=c-archive</code>
-      or <code>c-shared</code>, when C code calls a Go function,
-      the <code>SIGPIPE</code> signal will be treated as usual for Go code.
-      In particular, when <code>SIGPIPE</code> is triggered by a write
-      to a closed Go network connection, it will not cause the program
-      to exit.
