| Gnulib module: pipe2 |
| |
| Portability problems fixed by Gnulib: |
| @itemize |
| @item |
| This function is missing on many non-glibc platforms: |
| glibc 2.8, Mac OS X 10.5, FreeBSD 6.0, NetBSD 5.0, OpenBSD 3.8, Minix 3.1.8, AIX 5.1, HP-UX 11, IRIX 6.5, 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: |
| @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 |
| |
| Note: This function portably supports the @code{O_NONBLOCK} flag only if the |
| gnulib module @code{nonblocking} is also used. |
