pub fn pipe2(flags: OFlag) -> Result<(RawFd, RawFd)>

The portability is definied by:

#[cfg(any(target_os = "android", target_os = "dragonfly", target_os =
"emscripten", target_os = "freebsd", target_os = "illumos", target_os =
"linux", target_os = "redox", target_os = "netbsd", target_os = "openbsd",
target_os = "solaris"))]

Documentation

Like pipe, but allows setting certain file descriptor flags.

The following flags are supported, and will be set atomically as the pipe is created:

O_CLOEXEC: Set the close-on-exec flag for the new file descriptors.
O_DIRECT: Create a pipe that performs I/O in “packet” mode.
O_NONBLOCK: Set the non-blocking flag for the ends of the pipe.
