[−][src]Function nix::unistd::mkfifo
pub fn mkfifo<P: ?Sized + NixPath>(path: &P, mode: Mode) -> Result<()>
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
extern crate tempfile; extern crate nix; use nix::unistd; use nix::sys::stat; use tempfile::tempdir; fn main() { 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), } }
