impl Platform for Sys

fn get_term_settings(terminal: UnixFileDesc) -> Result<UnixTermSettings, Error>

If terminal is a terminal then get it’s term settings.

fn restore_terminal( term_settings: &UnixTermSettings, shell_pid: UnixPid, ) -> Result<(), Error>

Restore terminal settings and put the shell back into the foreground.

fn terminal_foreground(terminal: UnixFileDesc)

Put terminal in the foreground, loop until this succeeds. Used during shell startup.

fn set_self_pgroup() -> Result<(), Error>

Puts the running process into its own process group. Do this during shell initialization.

fn grab_terminal(terminal: UnixFileDesc) -> Result<(), Error>

Grab control of terminal. Used for shell startup.

fn anon_pipe() -> Result<(UnixFileDesc, UnixFileDesc), Error>

Return the input and output file descriptors for an anonymous pipe.

fn close_fd(fd: UnixFileDesc) -> Result<(), Error>

Close a raw Unix file descriptor.

fn foreground_job( job: &mut Job, term_settings: &Option<UnixTermSettings>, ) -> Result<(), Error>

Move the job for job_num to te foreground.

fn background_job(job: &mut Job) -> Result<(), Error>

Move the job for job_num to te background and running (start a stopped job in the background).

fn dup2_fd( src_fd: UnixFileDesc, dst_fd: UnixFileDesc, ) -> Result<UnixFileDesc, Error>

Duplicate a raw file descriptor to another file descriptor.

fn getpid() -> UnixPid

Get the current PID.

fn gethostname() -> Option<OsString>

Get the current machines hostname if available.

fn current_uid() -> u32

Get current UID of the process.

fn effective_uid() -> u32

Get effective UID of the process.

type Pid = UnixPid

type FileDesc = UnixFileDesc

type TermSettings = UnixTermSettings

fn fork_run(run: &Run, job: &mut Job, jobs: &mut Jobs) -> Result<(), Error>

fn fork_exec( command: &CommandWithArgs, job: &mut Job, jobs: &mut Jobs, ) -> Result<(), Error>

fn try_wait_pid(pid: UnixPid, job: &mut Job) -> (bool, Option<i32>)

fn wait_job(job: &mut Job) -> Option<i32>

fn is_tty(terminal: UnixFileDesc) -> bool

fn set_rlimit(rlimit: RLimit, values: RLimitVals) -> Result<(), Error>

fn get_rlimit(rlimit: RLimit) -> Result<RLimitVals, Error>

fn merge_and_set_umask( current_umask: mode_t, mask_string: &str, ) -> Result<mode_t, Error>

If mask_string is a mode string then merge it with umask and set the current umask. If mask_string is an int then treat it as a umask and set the current umask (no merge)).

fn get_and_clear_umask() -> mode_t

Clears the current umask and returns the previous umask.

fn set_umask(umask: mode_t) -> Result<(), Error>

Set current umask to umask.

fn to_octal_string(mode: mode_t) -> Result<String, Error>

Convert mode to the octal string umask format.
