pub fn unix_open_pipe(flags: i32) -> Result<(RawFd, RawFd), Error>
Expand description

Similar to the UNIX pipe() call, but on modern systems like Linux uses the pipe2() system call, which atomically creates a pipe with the configured flags. The only supported flag currently is FD_CLOEXEC. If for example you want to configure O_NONBLOCK, that must still be done separately with fcntl().

This function does not take O_CLOEXEC, it takes FD_CLOEXEC as if for fcntl(); these are different on Linux/glibc.

fds

Array of two integers

flags

Bitfield of file descriptor flags, as for fcntl()

Returns

true on success, false if not (and errno will be set).
