@node pipe2 @subsection @code{pipe2} @findex pipe2 POSIX specification:@* @url{https://pubs.opengroup.org/onlinepubs/9799919799/functions/pipe2.html} Documentation:@* @uref{https://www.kernel.org/doc/man-pages/online/pages/man2/pipe2.2.html,,man pipe2} Gnulib module: pipe2 @mindex pipe2 Portability problems fixed by Gnulib: @itemize @item This function is missing on many non-glibc platforms: glibc 2.8, macOS 14, FreeBSD 6.0, NetBSD 5.0, OpenBSD 3.8, Minix 3.1.8, AIX 5.1, HP-UX 11, Solaris 11.3, Cygwin 1.7.1, mingw, MSVC 14, Android 2.2. But the replacement function is not atomic; this matters in multi-threaded programs that spawn child processes. @end itemize Portability problems not fixed by Gnulib: @itemize @item This function crashes rather than failing with @code{EMFILE} if no resources are left on some platforms: Cygwin 1.7.9. @end itemize @mindex nonblocking Note: This function portably supports the @code{O_NONBLOCK} flag only if the gnulib module @code{nonblocking} is also used.
