pub fn reinit(self) -> Result<PosixSpawnFileActions>

Reinitialize the spawn file actions object. This is a wrapper around posix_spawn_file_actions_destroy. followed by posix_spawn_file_actions_init.

pub fn add_dup2(&mut self, fd: RawFd, newfd: RawFd) -> Result<()>

Add a dup2 action. See posix_spawn_file_actions_adddup2.

pub fn add_open<P: ?Sized + NixPath>( &mut self, fd: RawFd, path: &P, oflag: OFlag, mode: Mode, ) -> Result<()>

Add an open action. See posix_spawn_file_actions_addopen.

pub fn add_close(&mut self, fd: RawFd) -> Result<()>

Add a close action. See posix_spawn_file_actions_addclose.

pub fn add_chdir<P: ?Sized + NixPath>(&mut self, path: &P) -> Result<()>

pub fn add_fchdir(&mut self, fd: RawFd) -> Result<()>
