Definitions

kill : PidT -> Signal -> EPrim ()

  Sends a signal to a running process or a group of processes.

Totality: total
Visibility: export

raise : Signal -> PrimIO ()

  Sends a signal to the calling thread.

Totality: total
Visibility: export

sigqueue : PidT -> Signal -> CInt -> EPrim ()

  Sends a realtime signal plus data word to a running process.
  
  Note that `sig` must be in the range [SIGRTMIN, SIGRTMAX].

Totality: total
Visibility: export

sigprocmask_ : How -> SigsetT -> PrimIO SigsetT

  Adjust the process signal mask according to the given `How`
  and signal set.
  
  Note: This allocates a new `sigset_t` pointer and returns the
        previously set signal mask. Client code is responsible to
        free the memory for this once it is no longer used.
        See also `sigprocmask` for a version that does not return
        the previous signal mask.

Totality: total
Visibility: export

abort : PrimIO ()

  Terminates the application by raising `SIGABRT` and dumps core.
  
  While `SIGABRT` can be handled with a signal handler, `abort` is
  still guaranteed successfully terminate the process.

pause : EPrim ()

  Suspends the current thread until a non-blocked signal is encountered.

Totality: total
Visibility: export

sigsuspend_ : SigsetT -> EPrim ()

  Atomically blocks the signals in `set`, then
  pauses the thread (see `pause`) and restores the signal set
  afterwards.

Totality: total
Visibility: export

sigwaitinfo_ : SigsetT -> SiginfoT -> EPrim ()

  Synchronously awaits one of the signals in `set`.
  
  Note: Usually, the signals in `set` should first be blocked via
        `sigprocmask`.

Totality: total
Visibility: export

sigwait_ : SigsetT -> EPrim Signal

  Synchronously awaits one of the signals in `set`.
  
  This is like `sigwaitinfo` but with a simpler API.

Totality: total
Visibility: export

sigtimedwait : SigsetT -> SiginfoT -> TimeT -> NsecT -> EPrim ()

  Like `sigwaitinfo` but times out with `EAGAIN` after `sec` seconds and
  `nsec` nanoseconds.

Totality: total
Visibility: export

sigprocmask : How -> List Signal -> EPrim ()

  Like `sigprocmask_` but does not allocate a pointer for the
  previous `sigset_t`.

Totality: total
Visibility: export

siggetprocmask : PrimIO (List Signal)

  Returns the current signal mask of the process.

Totality: total
Visibility: export

sigpending : PrimIO (List Signal)

  Returns the set of currently pending signals.

Totality: total
Visibility: export

sigsuspend : List Signal -> EPrim ()

  Convenience alias for `sigsuspend_`

Totality: total

sigwait : List Signal -> EPrim Signal

  Convenience alias for `sigwait_`.

Totality: total

sigwaitinfo : List Signal -> EPrim Siginfo

  Convenience alias for `sigwaitinfo_`.
