pub fn mkfifo<P: ?Sized + NixPath>(path: &P, mode: Mode) -> Result<()>
Expand description
Creates new fifo special file (named pipe) with path path
and access rights mode
.
Errors
There are several situations where mkfifo might fail:
- current user has insufficient rights in the parent directory
- the path already exists
- the path name is too long (longer than
PATH_MAX
, usually 4096 on linux, 1024 on OS X)

Example
use nix::unistd;
use nix::sys::stat;
use tempfile::tempdir;
let tmp_dir = tempdir().unwrap();
let fifo_path = tmp_dir.path().join("foo.pipe");
// create new fifo and give read, write and execute rights to the owner
match unistd::mkfifo(&fifo_path, stat::Mode::S_IRWXU) {
Ok(_) => println!("created {:?}", fifo_path),
Err(err) => println!("Error creating fifo: {}", err),
}
