10.69.64 pipe2 ¶

POSIX specification:
https://pubs.opengroup.org/onlinepubs/9799919799/functions/pipe2.html

Documentation:
man pipe2

Gnulib module: pipe2

Portability problems fixed by Gnulib:

• 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.

Portability problems not fixed by Gnulib:

• This function crashes rather than failing with EMFILE if no resources are left on some platforms: Cygwin 1.7.9.

Note: This function portably supports the O_NONBLOCK flag only if the gnulib module nonblocking is also used.
